Isaias 46:4

31. But what did this profit me, supposing that Thou, O Lord God, the Truth, wert a bright and vast body, and I a piece of that body? Perverseness too great! But such was I. Nor do I blush, O my God, to confess to Thee Thy mercies towards me, and to call upon Thee, I, who blushed not then to avow before men my blasphemies, and to bark against Thee. What profited me then my nimble wit in those sciences and all those knotty volumes, disentangled by me without help from a human master, seeing that I erred so odiously, and with such sacrilegious baseness, in the doctrine of piety? Or what impediment was it to Thy little ones to have a far slower wit, seeing that they departed not far from Thee, that in the nest of Thy Church they might safely become fledged, and nourish the wings of charity by the food of a sound faith? O Lord our God, under the shadow of Thy wings let us hope, defend us, an …

But that the expression, “until,” spoken of God, and “unto,” do not signify an end, hear what one saith: “From everlasting unto everlasting Thou art God:” ( Ps. xc. 2 .) and again, “I am, I am,” and “Even to your old age I am He.” ( Is. xlvi. 4 .)

This reproach God spake against the Jews. “Borne from the belly, and instructed even to old age.” ( Isa. xlvi. 3, 4 , Sept.) If ye had not always been expecting this, all things would not have gone backward in this way. Had it been so, that some had finished learning, and others were about to have finished, our work would have been forward; ye would both have given place to others, and would have helped us as well. Tell me, were some to go to a grammarian and continue always learning their letters, would they not give their teacher much trouble? How long shall I have to discourse to you concerning life? In the Apostles’ times it was not thus, but they continually leaped from place to place, appointing those who first learned to be the teachers of any others that were under instruction. Thus they were enabled to circle the world, through not being bound to one place. …

6. Our reply is briefly this, the words knew and till in the language of Holy Scripture are capable of a double meaning. As to the former, he himself gave us a dissertation to show that it must be referred to sexual intercourse, and no one doubts that it is often used of the knowledge of the understanding, as, for instance, “the boy Jesus tarried behind in Jerusalem, and his parents knew it not.” Now we have to prove that just as in the one case he has followed the usage of Scripture, so with regard to the word till he is utterly refuted by the authority of the same Scripture, which often denotes by its use a fixed time (he himself told us so), frequently time without limitation, as when God by the mouth of the prophet says to certain persons, “Even to old age I am he.” Will He cease to be God when they have grown old? And the Saviour in the Gospel tells the Apostles, “Lo, I am with you …
