Osee 2:7

Chapter 16. 24. Some one says, Does it then make no difference, if two men, rooted in like error and wickedness, be baptized without change of life or heart, one without, the other within the Church? I acknowledge that there is a difference. For he is worse who is baptized without, in addition to his other sin, not because of his baptism, however, but because he is without; for the evil of division is in itself far from insignificant or trivial. Yet the difference exists only if he who is baptized within has desired to be within not for the sake of any earthly or temporal advantage, but because he has preferred the unity of the Church spread throughout the world to the divisions of schism; otherwise he too must be considered among those who are without. Let us therefore put the two cases in this way. …

1. I am induced to write to you, a stranger to a stranger, by the entreaties of that holy servant of Christ Hedibia and of my daughter in the faith Artemia, once your wife but now no longer your wife but your sister and fellow-servant. Not content with assuring her own salvation she has sought yours also, in former days at home and now in the holy places.

In speaking thus I do not mean to sever the law from the gospel, as Marcion falsely does. No, I receive one and the same God in both who, as the time and the object vary, is both the Beginning and the End, who sows that He may reap, who plants that He may have somewhat to cut down, and who lays the foundation that in the fulness of time He may crown the edifice. Besides, if we are to deal with symbols and types of things to come, we must judge of them not by our own opinions but in the light of the apostle’s explanations. Hagar and Sarah, or Sinai and Zion, are typical of the two testaments. Leah who was tender-eyed and Rachel whom Jacob loved signify the synagogue and the church. So likewise do Hannah and Peninnah of whom the former, at first barren, afterwards exceeded the latter in fruitfulness. …

And this care of His and providence with regard to us the Divine word has finely described by the prophet Hosea under the figure of Jerusalem as an harlot, and inclining with disgraceful eagerness to the worship of idols, where when she says: “I will go after my lovers, who give me my bread, and my water, and my wool, and my flax, and my oil, and my drink;” the Divine consideration replies having regard to her salvation and not to her wishes: “Behold I will hedge up thy way with thorns, and I will stop it up with a wall, and she shall not find her paths. …
