Menaion

May 21

PolyeleosThe holy emperor Constantine and his mother Helen, equal to the apostles. Constantine reigned in ancient Rome and in Byzantium (which became New Rome), and was the first Christian emperor, champion of the Faith. Though he was not baptized until on his deathbed, he considered himself a Christian, and called the First Ecumenical Council at Nicea in 325 to settle the Arian heresy. (337) On the Via Labicana in old Rome, Helen, the mother of Constantine the emperor is remembered. She single-mindedly worked to help the needy and piously visited churches, mingling with the crowds. Having made a pilgrimage to Jerusalem to see the places of the Nativity, Passion, and Resurrection of Christ, she honored the manger and cross of the Lord by building basilicas worthy of respect. (327)
