Ver. 25. “And answereth to Jerusalem that now is.”
That is, it borders on, and is contiguous to it.
Ver. 25. “For she is in bondage with her children.”
What follows from hence? Not only that she was in bondage and brought forth bondmen, but that this Covenant is so too, whereof the bondwoman was a type. For Jerusalem is adjacent to the mountain of the same name with the bondwoman, and in this mountain the Covenant was delivered. Now where is the type of Sarah?
Ver. 26. “But Jerusalem that is above is free.”
Those therefore, who are born of her are not bondmen. Thus the type of the Jerusalem below was Hagar, as is plain from the mountain being so called; but of that which is above is the Church. Nevertheless he is not content with these types, but adds the testimony of Isaiah to what he has spoken. Having said that Jerusalem which is above “is our Mother,” and having given that name to the Church, he cites the suffrage of the Prophet in his favor,
Ver. 27. “Rejoice, thou barren that bearest not, break forth and cry, thou that travailest not, for more are the children of the desolate than of her which hath the husband.” (Isa. liv. 1.)
Who is this who before was “barren,” and “desolate?” Clearly it is the Church of the Gentiles, that was before deprived of the knowledge of God? Who, “she which hath the husband?” plainly the Synagogue. Yet the barren woman surpassed her in the number of her children, for the other embraces one nation, but the children of the Church have filled the country of the Greeks and of the Barbarians, the earth and sea, the whole habitable world. Observe how Sarah by acts, and the Prophet by words, have described the events about to befal us. Observe too, that he whom Isaiah called barren, Paul hath proved to have many children, which also happened typically in the case of Sarah. For she too, although barren, became the mother of a numerous progeny. This however does not suffice Paul, but he carefully follows out the mode whereby the barren woman became a mother, that in this particular likewise the type might harmonize with the truth. Wherefore he adds
Ver. 28. “Now we, brethren, as Isaac was, are children of promise.”
It is not merely that the Church was barren like Sarah, or became a mother of many children like her, but she bore them in the way Sarah did. As it was not nature but the promise of God which rendered Sarah a mother, [for the word of God which said, “At the time appointed I will return unto thee, and Sarah shall have a son,” (Gen. xviii. 14.) this entered into the womb and formed the babe,] so also in our regeneration it is not nature, but the Words of God spoken by the Priest, (the faithful know them,) which in the Bath of water as in a sort of womb, form and regenerate him who is baptized.
Wherefore if we are sons of the barren woman, then are we free. But what kind of freedom, it might be objected, is this, when the Jews seize and scourge the believers, and those who have this pretence of liberty are persecuted? for these things then occurred, in the persecution of the faithful. Neither let this disturb you, he replies, this also is anticipated in the type, for Isaac, who was free, was persecuted by Ishmael the bondman. Wherefore he adds,
Ver. 29, 30. “But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now. Howbeit what saith the Scripture? (Gen. xxi. 10.) Cast out the handmaid and her son: for the son of the handmaid shall not inherit with the son of the freewoman.”
What! does all this consolation consist in showing that freemen are persecuted by bond-men? By no means, he says, I do not stop here, listen to what follows, and then, if you be not pusillanimous under persecution, you will be sufficiently comforted. And what is it that follows? “Cast out the son of the handmaid, for he shall not inherit with the son of the freewoman.” Behold the reward of tyranny for a season, and of reckleness out of season! the son is cast out of his father’s house, and becomes, together with his mother, an exile and a wanderer. And consider too the wisdom of the remark; for he says not that he was cast forth merely because he persecuted, but that he should not be heir. For this punishment was not exacted from him on account of his temporary persecution, (for that would have been of little moment, and nothing to the point,) but he was not suffered to participate in the inheritance provided for the son. And this proves that, putting the persecution aside, this very thing had been typified from the beginning, and did not originate in the persecution, but in the purpose of God. Nor does he say, “the son of Abraham shall not be heir,” but, “the son of the handmaid,” distinguishing him by his inferior descent. Now Sarah was barren, and so is the Gentile Church; observe how the type is preserved in every particular, as the former, through all the by-gone years, conceived not, and in extreme old age became a mother, so the latter, when the fulness of time is come, brings forth. And this the prophets have proclaimed, saying, “Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not; for more are the children of the desolate than of her which hath the husband.” And hereby they intend the Church; for she knew not God, but as soon as she knew Him, she surpassed the fruitful synagogue.
Ver. 31. “Wherefore, brethren, we are not children of a handmaid but of the freewoman.”
He turns and discusses this on all sides, desiring to prove that what had taken place was no novelty, but had been before typified many ages ago. How then can it be otherwise than absurd for those who had been set apart so long and who had obtained freedom, willingly to subject themselves to the yoke of bondage?
Next he states another inducement to them to abide in his doctrine.
