Athanasius was one of the greatest fathers of the 4th-century Church. As a deacon he attended the council of *Nicaea (1) (325), and in 328 he was appointed bishop of *Alexandria (1). Athanasius faced immediate opposition from the Meletian Schism within Egypt, and particularly from those whom he regarded as supporters of *“Arianism”, the heresy condemned at Nicaea. These conflicts caused Athanasius to be exiled from his see on five separate occasions, but he never ceased to defend his conception of Christian orthodoxy, and became the foremost champion of the Nicene doctrine that Father and Son were consubstantial (homoousios). He also developed the doctrine of the full divinity of the Holy Spirit, promoted the spread of monasticism, notably through his Life of Antony, and greatly enhanced the power and prestige of the Alexandrian see. Athanasius’ surviving writings include apologetic, dogmatic, and ascetic treatises, and a number of letters.
