Good Day, PhilopateerMercurios
Yes he said it:
But what a thing it is, to assert and contend that they who are not born in the Church can be the sons of God! For the blessed apostle sets forth and proves that baptism is that wherein the old man dies and the new man is born, saying, 'He saved us by the washing of regeneration.' But if regeneration is in the washing, that is, in baptism, how can heresy, which is not the spouse of Christ, generate sons to God by Christ? For it is the Church alone which, conjoined and united with Christ, spiritually bears sons; as the same apostle again says, 'Christ loved the Church, and gave Himself for it, that He might sanctify it, cleansing it with the washing of water.' If, then, she is the beloved and spouse who alone is sanctified by Christ, and alone is cleansed by His washing, it is manifest that heresy, which is not the spouse of Christ, nor can be cleansed nor sanctified by His washing, cannot bear sons to God....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?...For it has been delivered to us, that there is one God, and one Christ, and one hope, and one faith, and one Church, and one baptism ordained only in the one Church, from which unity whosoever will depart must needs be found with heretics" - Cyprian (Letter 73:6-7, 73:11)
