Philosophy of The Middle Ages

Patristics of the 4th Century

The 4th century was a pivotal era in Christian history: in 313, Emperor Constantine the Great legalized Christianity within the Roman Empire, and by 380, Emperor Theodosius declared it the state religion. This newfound freedom spurred vigorous philosophical and theological debate, leading to the designation of the 4th century as the "Golden Age of Patristics."

A significant catalyst for theological and philosophical discussions was the rise of Arianism. The Alexandrian priest Arius began preaching that Jesus Christ was not God but merely the highest of God's creations. These claims provoked the foremost minds of the Christian world to combat the heresy, culminating in the First Council of Nicaea in 325, where delegates from across the Christian world gathered for theological deliberation. This event established the tradition of convening councils to resolve crucial church matters. The council condemned Arius and affirmed the Nicene Creed. The prominent Christian philosophers and theologians of the 4th century who opposed Arianism included:

• Athanasius the Great (293-373): The bishop of Alexandria, Athanasius became the leading theologian of the Christian East during the First Council of Nicaea. He distinguished between the Divine nature and will, explaining that God the Father begets the Son and sends the Spirit, while the world is created by His will.
• Basil the Great (c. 329-379): Notable for creating the first monastic rule, Basil laid the groundwork for future monasticism. He defended the official position of the Church as expressed at Nicaea and developed the doctrine of the consubstantiality of the Father and the Son, asserting that God is a single essence (ousia) with three persons (hypostases). In his treatise "Against Eunomius," Basil argued that God's essence is unknowable, a position that influenced subsequent epistemology. He contended that while humans can understand that God exists, they cannot grasp His essence.
• Gregory of Nazianzus: A close friend and ally of Basil and a leader of the First Council of Constantinople, Gregory engaged in debates against Apollinaris of Laodicea, who claimed that Christ, having taken human body and soul, did not assume the human spirit, replacing it with Himself. Gregory argued that Christ took on the entirety of human nature to effect salvation. His contributions to anthropology and the affirmation of human dignity included the concept of theosis (deification), or the ultimate assimilation of humanity to God.
• Gregory of Nyssa: The brother of Basil and a collaborator with Gregory of Nazianzus, Gregory of Nyssa hailed from Cappadocia (a Byzantine province in Asia Minor). The three Cappadocian Fathers were noted for considering philosophy a treasure bestowed upon Christians by Greek culture. Gregory used philosophical insights to support the Nicene doctrines and developed mystical theology, focusing on the mystical experience of God and the possibility of mystical communion with Him.
• John Chrysostom: Renowned as a distinguished preacher, John Chrysostom emphasized morality in his sermons, many of which were recorded by his listeners. He advocated for strict moral ideals and was a critic of the moral laxity within the Byzantine elite.

The 4th century also saw the flourishing of monastic literature, where authors, as ascetics, shared their experiences with those embarking on monastic or even lay spiritual paths. These works, including those of Evagrius Ponticus, Pachomius, and Macarius of Egypt, provided deep insights into human nature, the relationship between soul and body, and inner spiritual struggles.

The vigorous debate against Arianism led to the emergence of a new heresy: Pneumatomachians or "spirit-fighters," who accepted Christ as the second divine person but denied the divinity of the Holy Spirit. This heresy was a more benign extension of Arianism. In response, the Council of Constantinople in 381 was convened, condemning Pneumatomachianism and igniting a new wave of theological discussions.

Another significant issue for 4th-century Christian thinkers was the debate with the Donatists. During the persecutions under Emperor Diocletian, some Christians renounced their faith under duress but later sought to return to the Church. This request sparked heated debate. A faction led by the priest Donatus argued that those who had renounced their faith, even under torture, should not be readmitted to the Church. This strict position did not gain widespread support, and the prevailing view became that Christians should approach the fallen with mercy.
