With regard to baptism, he taught in accordance with the received belief of his day that it is the sacrament of adoption and regeneration, wherein sin is forgiven, De Pœn. I. 36. and the Holy Spirit confers new life upon the soul and joins it mystically to Christ. As to the Real Presence in the Sacrament of the Eucharist, his doctrine is no less definite. In his treatise on the Faith he says of the elements that they “are transfigured [transfigurantur] For the force of the word transfigurantur in early ecclesiastical Latin, compare Tertullian, adv. Praxeam, c. 27: “Transfiguratio interremptio est pristini. Omne enim, quodcunque transfiguratur in aliud desinit esse quod fuerat, et incipit esse quod non erat.” by the mystery of the sacred prayer into flesh and blood.” De Fid. IV. 124. He interprets various texts, also, in many places in the same sense. In a like spirit he maintains that the power of forgiving sins on repentance is vested in the ministry of the Church. De Pœn. II. 12, etc. The intercession of the saints, and up to a certain point their invocation, is likewise upheld. Ep. 22 De ob. Theod. 41–51; De Viduis., 55.
