CHAP. XV.--23. For it is the Church that gives birth to all, either within her pale, of her own womb; or beyond it, of the seed of her bridegroom,--either of herself, or of her handmaid. But Esau, even though born of the lawful wife, was separated from the people of God because he quarrelled with his brother. And Asher, born indeed by the authority of a wife, but yet of a handmaid, was admitted to the land of promise on account of his brotherly good-will. Whence also it was not the being born of a handmaid, but his quarrelling with his brother, that stood in the way of Ishmael, to cause his separation from the people of God; and he received no benefit from the power of the wife, whose son he rather was, inasmuch as it was in virtue of her conjugal rights that he was both conceived in and born of the womb of the handmaid. Just as with the Donatists it is by the right of the Church, which exists in baptism, that whosoever is born receives his birth; but if they agree with their brethren, through the unity of peace they come to the land of promise, not to be again cast out from the bosom of their true mother, but to be acknowledged in the seed of their father; but if they persevere in discord, they will belong to the line of Ishmael. For Ishmael was first, and then Isaac; and Esau was the elder, Jacob the younger. Not that heresy gives birth before the Church, or that the Church herself gives birth first to those who are carnal or animal, and afterwards to those who are spiritual; but because, in the actual lot of our mortality, in which we are born of the seed of Adam, "that was not first which is spiritual, but that which is natural, and afterward that which is spiritual."[43] But from mere animal sensation, because "the natural man receiveth not the things of the Spirit of God,"[44] arise all dissensions and schisms. And the apostle says[45] that all who persevere in this animal sensation belong to the old covenant, that is, to the desire of earthly promises, which are indeed the type of the spiritual; but "the natural man receiveth not the things of the Spirit of God."[44]
