On the Feast of St John the Evangelist, the great Apostle of the Incarnation, an extract from the third chapter of St Athanasius’s great treatise De Incarnatione. Athanasius was Bishop of Alexandria in the turbulent fourth century; he doughtily refuted the false teachings of the heresiarch Arius, and for his defence of the doctrine of the Incarnation he is numbered among the Doctors of the Church. Newman called him “ principal instrument, after the Apostles, by which the sacred truths of Christianity have been conveyed and secured to the world.”
