St. Macarius of Jerusalem (4th c.) was the Bishop of Jerusalem from 312-335 A.D. Little is known of his life before this time. He took part in the Council of Nicea in 325 A.D. and vigorously opposed the Arian heresy, which greatly threatened the early Church. It is believed that he was one of the bishops who helped draft the Nicene Creed. St. Athanasius, his contemporary, refers to Macarius as an example of “the honest and simple style of apostolical men.”
After the council, St. Macarius accompanied St. Helen, the queen mother of the Roman Emperor Constantine, in her successful search for the True Cross that Jesus was crucified upon. It was he who suggested to St. Helen that she would identify the real Cross by touching all three of those she found to a seriously ill woman, and observe which one brought immediate healing.
Following the discovery of the True Cross in this miraculous manner, Constantine wrote to Bishop Macarius requesting that he oversee the construction of a magnificent church in Jerusalem, the Basilica of the Holy Sepulchre, to commemorate the sites of the Crucifixion and Burial of Christ, which still exists today as one of the most important Christian pilgrimage sites in the world. His feast day is March 10th.
