her own womb, and in the womb of her handmaids, by virtue of the same sacraments, as though by virtue of the seed of her husband. For it is not without meaning that the apostle says that all these things were done by way of figure.[31] But those who are too proud, and are not joined to their lawful mother, are like Ishmael, of whom it is said, "Cast out this bond-woman and her son: for the son of the bond-woman shall not be heir with my son, even with Isaac."[32] But those who peacefully love the lawful wife of their father, whose sons they are by lawful descent, are like the sons of Jacob, born indeed of handmaids, but yet receiving the same inheritance.[33] But those who are born within the family, of the womb of the mother herself, and then neglect what they have received, are like Isaac's son Esau, who was rejected, God Himself bearing witness to it, and saying, "I loved Jacob, and I hated Esau;"[34] and that though they were twin-brethren, the offspring of the same womb. * * * * * CHAP. XI.--15. They ask also, "Whether sins are remitted in baptism in the party of Donatus:" so that, if we say that they are remitted, they may answer, then the Holy Spirit is there; for when by the breathing of our Lord the Holy Spirit was given to the disciples, He then went on to say, "Baptize all nations in the name of the Father, and of the Son, and of the Holy Ghost."[35] "Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained."[36] And if it is so, they say, then our communion is the Church of Christ; for the Holy Spirit does not work the remission of sins except in the Church. And if our communion is the Church of Christ, then your communion is not the Church of Christ. For that is one, wherever it is, of which it is said, "My dove is but one; she is the only one of her mother;"[37] nor can there be just so many churches as there are schisms. But if we should say that sins are not there remitted, then, say they, there is no true baptism there; and therefore ought you to baptize those whom you receive from us. And since you do not do this, you confess that you are not in the Church of Christ.
