Euchratius of Thenæ said: God and our Lord Jesus Christ, teaching the apostles with His own mouth, has entirely completed our faith, and the grace of baptism, and the rule of the ecclesiastical law, saying: “Go ye and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.” Thus the false and wicked baptism of heretics must be rejected by us, and refuted with all detestation, from whose mouth is expressed poison, not life, not celestial grace, but blasphemy of the Trinity. And therefore it is manifest that heretics who come to the Church ought to be baptized with the sound and Catholic baptism, in order that, being purified from the blasphemy of their presumption, they may be reformed by the grace of the Holy Spirit.
