Romans 4:11

But let us proceed with our inquiry into some eminent chief fathers of our origin: for there are some to whom our monogamist parents Adam and Noah are not pleasing, nor perhaps Christ either. To Abraham, in fine, they appeal; prohibited though they are to acknowledge any other father than God. Grant, now, that Abraham is our father; grant, too, that Paul is. “In the Gospel,” says he, “I have begotten you.” Show yourself a son even of Abraham. For your origin in him, you must know, is not referable to every period of his life: there is a definite time at which he is your father. …

Thus the holy Virgin, while still in the flesh, maintained the incorruptible life, and received in faith the things which were announced by the archangel. And thereafter she journeyed diligently to her relation Elisabeth in the hill-country. “And she entered into the house of Zacharias, and saluted Elisabeth,” in imitation of the angel. “And it came to pass, that, when Elisabeth heard the salutation of Mary, the babe leapt with joy in her womb; and Elisabeth was filled with the Holy Ghost.” Thus the voice of Mary wrought with power, and filled Elisabeth with the Holy Ghost. And by her tongue, as from an ever-flowing fountain, she sent forth a stream of gracious gifts in the way of prophecy to her relation; and while the feet of her child were bound in the womb, she prepared to dance and leap. And that was the sign of a marvellous jubilation. …

“And this is the witness of John.” This is the second recorded testimony of John the Baptist to Christ. The first begins with “This was He of whom I said, He that cometh after me,” and goes down to “The only-begotten Son of God who is in the bosom of the Father, He hath declared him.” Heracleon supposes the words, “No one has seen God at any time,” etc., to have been spoken, not by the Baptist, but by the disciple. But in this he is not sound. He himself allows the words, “Of his fulness we all received, and grace for grace; for the law was given by Moses, but grace and truth came by Jesus Christ,” to have been spoken by the Baptist. …

47. But, it is said, if the prophets foretold Christ, they did not live in a way becoming their office. How can you tell whether they did or not? You are bad judges of what it is to live well or ill, whose justice consists in giving relief to an inanimate melon by eating it, instead of giving food to the starving beggar. It is enough for the babes in the Catholic Church, who do not yet know the perfect justice of the human soul, and the difference between the justice aimed at and that actually attained, to think of those men according to the wholesome doctrine of the apostles, that the just lives by faith. "Abraham believed God, and it was counted to him for righteousness. For the scripture, foreseeing that God would justify the Gentiles by faith, preached before the gospel unto Abraham, saying, In thy seed shall all nations be blessed." These are the words of the apostle. …

29. Unless Christ had considered this Sabbath, which in your want of knowledge and of piety you laugh at, one of the prophecies written of Himself, He would not have borne such a testimony to it as He did. For when, as you say in praise of Christ, He suffered voluntarily, and so could choose His own time for suffering and for resurrection, He brought it about that His body rested from all its works on Sabbath in the tomb, and that His resurrection on the third day, which we call the Lord’s day, the day after the Sabbath, and therefore the eighth, proved the circumcision of the eighth day to be also prophetical of Him. …

Chapter 24. 32. And if any one seek for divine authority in this matter, though what is held by the whole Church, and that not as instituted by Councils, but as a matter of invariable custom, is rightly held to have been handed down by apostolical authority, still we can form a true conjecture of the value of the sacrament of baptism in the case of infants, from the parallel of circumcision, which was received by God’s earlier people, and before receiving which Abraham was justified, as Cornelius also was enriched with the gift of the Holy Spirit before he was baptized. …

The Scripture does not inform us whether before Abraham’s time righteous men or their children were marked by any bodily or visible sign. Abraham himself, indeed, received the sign of circumcision, a seal of the righteousness of faith. And he received it with this accompanying injunction: All the male infants of his household were from that very time to be circumcised, while fresh from their mother’s womb, on the eighth day from their birth; so that even they who were not yet able with the heart to believe unto righteousness, should nevertheless receive the seal of the righteousness of faith. …

But let him inform us how it was that his soul would be cut off from his people if he had not been circumcised on the eighth day. How could he have so sinned, how so offended God, as to be punished for the neglect of others towards him with so severe a sentence, had there been no original sin in the case? For thus ran the commandment of God concerning the circumcision of infants: “The uncircumcised man-child, whose flesh of his foreskin is not circumcised on the eighth day, his soul shall be cut off from his people; because he hath broken my covenant.” Let him tell us, if he can, how that child broke God’s covenant, an innocent babe, so far as he was personally concerned, of eight days’ age; and yet there is by no means any falsehood uttered here by God or Holy Scripture. …

Ver. 11 . “He received it,” he says, “a sign and seal of the righteousness that was by the faith, which he had being yet uncircumcised.” See you how he shows the Jews to be as it were of the class of parasites (i.e. guests), rather than those in uncircumcision, and that these were added to the others? For if he was justified and crowned while in uncircumcision, the Jews came in afterwards, Abraham is then the father first of the uncircumcised, which through faith appertain to him, and then of those in the circumcision. For he is a forefather of two lines. See you faith lightening up? for till it came the patriarch was not justified. See you the uncircumcision offering no hindrance? for he was uncircumcised, yet was not hindered from being justified. The circumcision therefore is behind the faith. And why wonder that it is behind the faith, when it is even behind the uncircumcision. …

4. Why did Abraham receive circumcision as a seal of his faith? ( Rom. iv. 11 .)

5. There is much to tell of faith, and the whole day would not be time sufficient for us to describe it fully. At present let us be content with Abraham only, as one of the examples from the Old Testament, seeing that we have been made his sons through faith. He was justified not only by works, but also by faith: for though he did many things well, yet he was never called the friend of God, except when he believed. Moreover, his every work was performed in faith. Through faith he left his parents; left country, and place, and home through faith. In like manner, therefore, as he was justified be thou justified also. In his body he was already dead in regard to offspring, and Sarah his wife was now old, and there was no hope left of having children. …
