When the empire wanted unity-at-the-cost-of-doctrine, he chose doctrine and lost everything. He had attended the Council of Nicaea in 325 as a young deacon and secretary to Bishop Alexander; he did not call the council, but after it chose homoousios ('of one substance') he became the council's fiercest defender. The point was simple and enormous: if the Son is not truly God, the gospel cannot say that God himself has come to save us. That is why the Creed says the Son is 'one in being with the Father' rather than a created being close to God. Read On the Incarnation next: it is short, clear, and still the best first answer to 'why did God become man.' C.S. Lewis loved it enough to write the famous introduction, where he advised reading one old book for every three modern ones.","feast_day_catholic":"05-02","feast_day_orthodox":"01-18"},{"id":"macarius-the-great","name":"Macarius the Great","alt_names":["Macarius of Egypt"],"born":300,"born_circa":true,"died":391,"died_circa":true,"birth_place":"Shabsheer","death_place":"Scetis","region":"egypt","role":["monk","presbyter"],"tradition_status":"desert-father","significance":2,"short_bio":"Egyptian desert father, founder of the monastic settlement of Scetis.
