Saint Athanasius (c. 295 – 373 AD) served as the Bishop of Alexandria and is recognized as one of the four great Eastern Doctors of the Church, playing a pivotal role in the early Church's theological development. He is most celebrated for his tenacious and lifelong defense of orthodox Trinitarian doctrine, affirming the full divinity of Jesus Christ against the widespread Arian heresy, which denied Christ's co-equality with God the Father. Despite facing immense opposition, including five periods of exile and persecution from emperors and fellow bishops, Athanasius steadfastly upheld the Nicene Creed, famously encapsulated in the phrase "Athanasius contra mundum" (Athanasius against the world). His theological writings, particularly *On the Incarnation of the Word*, profoundly shaped Christian understanding of the Incarnation and the Trinity, solidifying the Church's foundational beliefs and earning him the title "Pillar of Orthodoxy."

Hagiography

Saint Athanasius, Bishop of Alexandria and Doctor of the Church, was one of the most formidable and influential figures in early Christian history, whose life was inextricably linked with the defense of orthodox belief against the widespread Arian heresy. Born in Alexandria, Egypt, around 295 AD, Athanasius received a comprehensive education, excelling in rhetoric, philosophy, and theology. His early formation was also significantly influenced by the burgeoning monastic movement, particularly through his close association with Saint Anthony the Great, the father of Christian monasticism, whose biography Athanasius would later famously pen. This blend of intellectual rigor and spiritual depth prepared him for the monumental theological battles that lay ahead, shaping him into a tenacious defender of the faith from a young age. His profound understanding of Scripture and the apostolic tradition laid the groundwork for his lifelong commitment to proclaiming the full divinity of Jesus Christ.

His intellectual prowess and theological acumen became evident early in his ecclesiastical career. As a young deacon, he served as secretary to Bishop Alexander of Alexandria. In this capacity, he accompanied Bishop Alexander to the First Ecumenical Council of Nicaea in 325 AD, a pivotal moment in Christian history. Though only in his late twenties, Athanasius played a crucial role in the debates, passionately advocating for the Nicene Creed's central tenet: that Jesus Christ is "homoousios" – of the same substance – with God the Father. This declaration directly countered the Arian teaching, which asserted that Christ was a created being, subordinate to the Father, thereby undermining the very foundation of Christian salvation. Athanasius's clear articulation and unwavering support for the Nicene formulation demonstrated his precocious theological genius and his deep conviction regarding the true nature of God.

Following Bishop Alexander's death in 328 AD, Athanasius, despite his youth, was overwhelmingly elected as his successor to the See of Alexandria, a position of immense influence in the Eastern Church. His elevation, however, immediately plunged him into a relentless struggle against the resurgent Arian faction. The Arians, with significant political backing from various emperors and even some bishops, sought to undermine the Nicene Creed and restore their theological views. Athanasius, now the chief shepherd of Alexandria, refused to compromise on what he considered to be the fundamental truth of the Christian faith. His steadfast opposition to Arianism, often a solitary stand against powerful adversaries, earned him the famous moniker "Athanasius contra mundum" – Athanasius against the world.

His unwavering fidelity to orthodoxy came at a tremendous personal cost. Over the course of his 45-year episcopate, Athanasius endured five periods of exile, totaling nearly seventeen years, often fleeing for his life across deserts and seeking refuge in distant lands. His first exile, from 335 to 337 AD, saw him banished to Trier (modern-day Germany) by Emperor Constantine, largely due to false accusations orchestrated by his Arian opponents. These exiles were not merely political banishments; they were spiritual trials, designed to break his resolve and silence his voice. Yet, with each return to his see, Athanasius resumed his vigorous defense of the Nicene faith, demonstrating an indomitable spirit and profound trust in divine providence.

During his various exiles, Athanasius was not idle. He utilized these periods of forced itinerancy to write some of his most significant theological works, which further solidified Nicene orthodoxy. His treatises *On the Incarnation of the Word* and *Against the Arians* became foundational texts for understanding the Incarnation and the Holy Trinity. In *On the Incarnation*, he eloquently articulated the doctrine that God became man so that humanity might become deified, a concept central to Eastern Christian theology. His writings were not merely academic; they were pastoral, aimed at instructing the faithful and equipping them to discern truth from error. He also maintained extensive correspondence, encouraging beleaguered bishops and offering theological guidance, thus shaping the theological landscape of the entire Christian world.

Towards the end of his life, the tide began to turn in favor of Nicene orthodoxy, largely due to Athanasius's tireless efforts and intellectual clarity. After years of persecution and exile, he returned to Alexandria for the final time in 366 AD, where he was able to guide his flock in relative peace until his death in 373 AD. His perseverance ensured that the Nicene Creed, the bedrock of Trinitarian theology, would ultimately prevail. Saint Athanasius is revered as a Pillar of Orthodoxy, a courageous bishop who prioritized divine truth above personal safety or political expediency. His legacy as a Doctor of the Church is not merely historical; it serves as an enduring inspiration for all Christians to uphold the integrity of the faith, to defend the divinity of Christ, and to live lives of unwavering commitment to truth, even in the face of overwhelming opposition.

The River's Deception

The city of Alexandria was once again a cauldron of intrigue and danger for its steadfast shepherd, Athanasius. Emperor Julian, known as the Apostate for his rejection of Christianity, had issued a decree for Athanasius's capture, declaring him a dangerous enemy to the state. Imperial soldiers, swift and merciless, scoured the city, determined to seize the bishop who had so defiantly upheld the Nicene faith. Athanasius, ever vigilant but undaunted, knew his time in the city was short.

As the sun dipped below the horizon, casting long shadows over the bustling port, Athanasius, with a few trusted companions, slipped quietly aboard a small boat on the River Nile. Their plan was to escape upstream, seeking refuge in the monastic communities of Upper Egypt, where his spiritual sons, the monks, would surely protect him. The air was thick with the scent of the river and the unspoken tension of their desperate flight.

They had not gone far when, in the dim twilight, the unmistakable sound of oars churning water grew louder behind them. A larger, faster vessel, bearing the imperial standard, was rapidly gaining on them. Panic began to ripple through Athanasius’s companions. The soldiers were close enough now for their shouts to be heard across the water. It seemed capture was inevitable.

But Athanasius, his face calm and resolute amidst the rising fear, turned to his boatmen. “Turn the boat around,” he commanded, his voice steady. “Row swiftly back towards Alexandria.” His companions were bewildered, but their trust in their bishop was absolute. The small boat spun about, now heading directly towards their pursuers, who were still rowing furiously upstream, expecting Athanasius to be fleeing in the opposite direction.

As the imperial boat drew alongside, the soldiers, their faces grim and eager for their prize, shouted, “Have you seen Athanasius? Which way did he go?” Athanasius, his head bowed slightly, his face obscured, replied with a calm voice, “He is not far from here. Row on, and you will soon overtake him!” Misled by the seemingly helpful advice and the unexpected sight of a boat returning, the soldiers, without a moment's hesitation, pressed on upstream with renewed vigor, convinced they were hot on Athanasius's trail.

Athanasius and his companions, having successfully diverted their pursuers, quietly rowed back to Alexandria. There, he disembarked and found a hidden place of refuge, likely among the very monks he had intended to visit, until the immediate danger passed. This ingenious escape, born of holy prudence and unwavering faith, became a testament to Athanasius’s character: a man of profound courage, sharp intellect, and absolute trust in the divine providence that so often intervened to protect him for the sake of the Church he served.

Writings by Saint Athanasius, Bishop, Doctor
On the Incarnation of the Word (Chapters 6-10)

c. 318-326 AD

6. For this reason, then, when the minds of men were thus declining, and God the Word was calling them back to Himself, He took to Himself a body, and that not from outside, but His own, fashioned from the Virgin, by the Holy Spirit. And He built it for Himself as a temple, and made it His very own as an instrument, in it to dwell and therein to make Himself known. For whereas from the transgression of the first man, the human race had become subject to corruption, and death had laid hold upon all, the incorruptible Word of God, coming into our nature, and uniting Himself to a body like ours, thereby opened the way of life to all men. For by His Incarnation, He became the first-fruits of a new creation, and in His own person, He brought to nought the power of death and corruption. So that, as by one man's disobedience sin entered into the world, and death by sin, so also by the obedience of one man, righteousness entered into the world, and life by righteousness. And thus it was that the Word, by taking a body, and by offering it as a sacrifice for all, put an end to death, and made life immortal available to all.

7. For this purpose, then, the incorruptible and incorporeal and immaterial Word of God comes to our realm, howbeit He was not far from us before. For no part of creation is left void of Him; He fills all things everywhere, remaining in His own nature, and not being contained, but containing all. But He comes, to our realm, as a loving Father, to save us from the corruption which has seized us. So He sees the whole race of men on the way to ruin, and death in full sway over them. He sees too that their transgressions have increased, and that the penalty of death for them is inevitable; for it was impossible that the law should be broken, and that God's word should fail. He sees too the unfittingness of it; that what was once rational, and had partaken of the Word, should perish, and that the works of God should disappear. He sees the exceeding wickedness of men, and how they had fallen away, and how they had become subject to the dominion of death. He sees too that the human race, which God had made rational, was being corrupted and destroyed by death, and that the image of God was being effaced. He sees that the very purpose for which He had made them was being frustrated, and that they were being reduced to the state of irrational animals. He sees that the world was full of unrighteousness and corruption, and that men were becoming more and more estranged from God. He sees that the human race, which had been created in the image of God, was being destroyed, and that the works of God were being brought to nought.

8. What then was God, being so good, to do? Was He to let corruption and death have their way with men, and destroy the image of God in them? In that case, what would have been the use of having made them at all? Or what point in having given them reason, if they were to perish like irrational creatures? It would have been better for them not to have been created at all, than to have been created only to perish. But if He allowed them to perish, then His goodness would have been called into question, and His wisdom too; for it would have seemed as if He had made them in vain. And if He had allowed them to be destroyed, then His power would have been called into question too; for it would have seemed as if He had been unable to save them. But He is good, and not only good, but also wise and powerful. So it was impossible for Him to allow His rational creatures to perish, and for His image to be destroyed. For this reason, then, the incorruptible Word of God, seeing that corruption could not be otherwise done away with than by the death of all, and knowing that the Word could not die, being immortal and the Father's Son, yet for this very reason takes to Himself a body capable of death, that it, by partaking of the Word Who is above all, might be worthy to die in place of all, and might, because of the indwelling Word, remain incorruptible, and that thus the corruption of all might be stayed by the incorruption of the Word dwelling in it. Thus, by a single offering of Himself, He put an end to death for all, and restored life to all, by the promise of the resurrection.

9. For, as the Word was not only incorporeal but also immortal, and as the Father's only-begotten Son, He could not Himself die. But since it was necessary that all should die, and that their corruption should be done away with, He therefore, as I have said, takes a body capable of death, that in it He might die for all, and that thus the curse due to all might be removed. For by His death, He put an end to death for all, and made life immortal available to all. For He was made man that we might be made God; and He manifested Himself through a body that we might receive the idea of the unseen Father; and He endured the insolence of men that we might inherit immortality. For He was reviled, and did not revile again; He suffered, and did not threaten; He was led as a lamb to the slaughter, and as a sheep before her shearers is dumb, so He opened not His mouth. For He was made man that we might be made God. And He endured the cross, despising the shame, that He might bring us to glory. For He was made man that we might be made God.

10. For by the sacrifice of His own body, He both put an end to the law of death which was against us, and made a new beginning of life possible for us, by giving us the hope of the resurrection. For since from man came death, so also from man came the resurrection of the dead. For since by one man's disobedience sin entered into the world, and death by sin, so also by the obedience of one man, righteousness entered into the world, and life by righteousness. And thus it was that the Word, by taking a body, and by offering it as a sacrifice for all, put an end to death, and made life immortal available to all. For He was made man that we might be made God. He assumed a mortal body, that He might destroy death, and renew life. For He was made man that we might be made God. He was born of a Virgin, that He might purify our birth. He was born in Bethlehem, that He might sanctify our earth. He was circumcised, that He might fulfill the law. He was baptized, that He might sanctify the water. He was tempted, that He might overcome the devil. He suffered, that He might heal our sufferings. He died, that He might destroy death. He rose again, that He might raise us up with Him. He ascended into heaven, that He might prepare a place for us. He sent the Holy Spirit, that He might dwell in us. He will come again, that He may judge the living and the dead. And thus, by all these things, He has made us partakers of His divine nature. For He was made man that we might be made God.

Oration 21: In Praise of Athanasius (Sections 5-10)

by Saint Gregory of Nazianzus

380 AD

5. What then was the great Athanasius? What were his characteristics? And what the virtues of this truly great and noble soul? He was, if I may speak briefly, virtue incarnate, and the very embodiment of God's Word. He was a pillar of the Church, a champion of truth, a model for priests, a mirror for kings, a rule of faith, a guide to perfection. He was a perfect example of what a bishop ought to be, a pattern of all episcopal virtues. He was a man of God, a divine man, a true servant of Christ. He was a man who lived in the flesh, but not according to the flesh; a man who was in the world, but not of the world. He was a man who possessed all virtues, and in whom all graces shone forth. He was a man who excelled in all things, and in whom there was no fault. He was a man who was loved by all, and feared by none. He was a man who was humble in spirit, but bold in deed; gentle in manner, but firm in resolve; calm in adversity, but fervent in zeal. He was a man who was a shepherd to his flock, a father to his children, a brother to his fellow-laborers, a friend to all. He was a man who was a burning and a shining light, a lamp that shone in a dark place, a star that guided men to Christ.

6. He was, above all, a man of God, a man filled with the Holy Spirit, a man who lived by faith, and who walked with God. He was a man of prayer, a man who communed with God, a man who sought God's will in all things. He was a man of humility, a man who esteemed others better than himself, a man who sought not his own glory, but the glory of God. He was a man of patience, a man who endured all things for Christ's sake, a man who suffered joyfully for the truth. He was a man of courage, a man who feared no man, a man who stood firm against all opposition. He was a man of wisdom, a man who knew the Scriptures, a man who understood the mysteries of God. He was a man of knowledge, a man who was learned in all things, a man who was able to confound the wise of this world. He was a man of eloquence, a man who spoke with grace and power, a man who was able to persuade men to embrace the truth. He was a man of charity, a man who loved all men, a man who sought the salvation of all.

7. His life was a continuous struggle, a perpetual warfare against the enemies of truth. He was persecuted by emperors, slandered by bishops, betrayed by friends, and hated by the world. He was driven from his see five times, and spent nearly seventeen years in exile. He was hunted like a wild beast, and forced to wander from place to place, seeking refuge in deserts, among monks, and in foreign lands. Yet, through all these trials, he remained steadfast in his faith, unwavering in his resolve, and unyielding in his defense of the truth. He was a true confessor of Christ, a martyr in spirit, a living sacrifice to God. He bore witness to the truth, not by shedding his blood, but by enduring countless sufferings for the sake of Christ. He was a man who loved truth more than life, and who esteemed the glory of God above all things.

8. And what was the cause of all these sufferings? What was the reason for all this persecution? It was his unwavering defense of the true faith, his steadfast adherence to the Nicene Creed, his unyielding opposition to the Arian heresy. He was the champion of the Son's consubstantiality with the Father, the defender of the Holy Trinity, the bulwark against heresy. He fought against the Arians with all his might, exposing their errors, refuting their arguments, and condemning their impiety. He was a true shepherd, who defended his flock from the wolves, and who laid down his life for his sheep. He was a true physician, who healed the sick, and who restored sight to the blind. He was a true light, who enlightened those who sat in darkness, and who guided them into the way of truth.

9. His zeal for God was unquenchable, his love for Christ was boundless, his devotion to the Church was absolute. He lived for Christ, he spoke for Christ, he suffered for Christ, he died for Christ. He was a man who consecrated his whole life to the service of God, and who dedicated all his energies to the defense of the truth. He was a man who was truly worthy of all praise, a man who was truly worthy of all honor, a man who was truly worthy of all veneration. He was a saint in every sense of the word, a man who attained to the highest degree of holiness, a man who was truly a friend of God. He was a man who was a model for all Christians, a man who was an example for all bishops, a man who was an inspiration for all ages.

10. Therefore, let us celebrate his memory with joy and thanksgiving, let us honor him with hymns and praises, let us imitate his virtues and follow his example. Let us learn from him to love truth, to defend the faith, to suffer for Christ, and to live for God. Let us strive to be like him, faithful servants of Christ, courageous defenders of truth, zealous champions of orthodoxy. For if we do these things, we shall not only honor him, but we shall also glorify God, and we shall secure for ourselves a place in the heavenly kingdom, where we shall join him in praising God for all eternity. Amen.
