First Reading · Genesis 17:3-9

3Abram fell flat on his face.4And God said to him: I am, and my covenant is with thee, and thou shalt be a father of many nations.5Neither shall thy name be called any more Abram: but thou shalt be called Abraham: because I have made thee a father of many nations.6And I will make thee increase exceedingly, and I will make nations of thee, and kings shall come out of thee.7And I will establish my covenant between me and thee, and between thy seed after thee in their generations, by a perpetual covenant: to be a God to thee, and to thy seed after thee.8And I will give to thee, and to thy seed, the land of thy sojournment, all the land of Chanaan, for a perpetual possession, and I will be their God.9Again God said to Abraham: And thou therefore shalt keep my covenant, and thy seed after thee in their generations.

commentary

God's first word to the man lying face down is a bare assertion of being: I am, and my covenant is with thee (v. 4). Du Hamel takes the clause at full strength — I am unchangeable, faithful to my promises, the only God — so that the covenant is anchored not in a plan but in a nature. What follows is a renaming, and Challoner supplies the sense of both forms: Abram in the Hebrew is a high father, Abraham the father of the multitude. The same operation is worked on his wife, and there the shift is smaller and sharper — Sarai means my Lady, Sara means Lady absolutely, the possessive simply dropped. Calmet reads the whole transaction as an adoption: God receives them, as it were, into his own family. A man face down in the dust is given a name he did not choose and cannot afterwards say without repeating the promise made in it.

The scope of many nations is contested, and Calmet answers generously: Jews, Saracens or Arabs, Idumeans, and then, by faith, all nations who believe in Christ, the King of kings. Worthington presses that into an argument about visibility. If the promise runs that wide, the true Church can never be reduced to a few unknown believers — which is what he takes the Donatists, and the Protestants of his own day, to be claiming. A promise of multitudes is not compatible with a remnant nobody can find. But Menochius will not let perpetual (v. 7) float free of conditions: the covenant lasts, he says, as long as they remain obedient, and he points to the verse that closes the reading for his warrant. Everything before v. 9 is God's own doing — I will make, I will establish, I will give — and then the grammar turns: thou therefore shalt keep my covenant, and thy seed after thee. One-sided in its origin, two-sided in its duration.

Both errors that the passage rebukes are still in circulation. One is the piety of the small faithful remnant, which finds a certain comfort in being unrecognized and mistakes obscurity for fidelity; Worthington's reply is simply to read the promise back, with its nations and its kings. The other is the reverse mistake, treating a covenant as an assurance already banked, when the last verse of the reading hands it back as something to be kept. What holds the two together is the new syllable in an old man's name. He did not add it, he could not have earned it, and he carried it for the rest of his life in front of everyone who spoke to him.

Haydock Catholic Bible Commentary · Public Domain
17:4

I am unchangeable, and faithful to my promises, the only God. (Du Hamel) --- Nations. Jews, Saracens or Arabs, Idumeans, and, by faith, of all nations who shall believe in Christ, the King of kings. (Calmet) --- The true Church will never then be reduced to a few unknown believers, as the Donatists and Protestants assert. (Worthington)

17:5

Abraham. Abram, in the Hebrew, signifies a high father; but Abraham, the father of the multitude: Sarai signifies my Lady, but Sara absolutely Lady. (Challoner) --- God thus receives them, as it were, into his own family. (Calmet)

17:7

Perpetual; that shall last as long as they remain obedient. (Menochius) (ver. 9.)
