St. Macarius was Bishop of Jerusalem from the early 300’s till his death about 325. He was a lifelong and staunch opponent of Arianism and fought strenuously against this pernicious heresy. He was present at the Council of Nicaea in 325 and played a large role in drafting the Creed.
Soon after the Council, together with St. Helena, Macarius miraculously discovered the true Cross in Jerusalem, and he was commissioned by her son, Emeror Constantine, to build the Church of the Holy Sepulcher. Later, he and his fellow Bishop of Palestine received another letter from Constantine to construct a church at Mamre.
PRAYER: God, Light and Shepherd of souls, You established St. Macarius as Bishop in Your Church to feed Your flock by his word and form it by his example. Help us through his intercession to keep the Faith he taught by his word and follow the way he showed by his example. Amen.
