7 But further, one is not born by the imposition of hands when he receives the Holy Ghost, but in baptism, that so, being already born, he may receive the Holy Spirit, even as it happened in the first man Adam. For first God formed him, and then breathed into his nostrils the breath of life. For the Spirit cannot be received, unless he who receives first have an existence. But as the birth of Christians is in baptism, while the generation and sanctification of baptism are with the spouse of Christ alone, who is able spiritually to conceive and to bear sons to God, where and of whom and to whom is he born, who is not a son of the Church, so as that he should have God as his Father, before he has had the Church for his Mother?
But as no heresy at all, and equally no schism, being without, can have the sanctification of saving baptism, why has the bitter obstinacy of our brother Stephen broken forth to such an extent, as to contend that sons are born to God from the baptism of Marcion; moreover, of Valentinus and Apelles, and of others who blaspheme against God the Father; and to say that remission of sins is granted in the name of Jesus Christ where blasphemy is uttered against the Father and against Christ the Lord God?
