“Ego et Pater unum sumus.”
“I and my Father are one.”
“I and the Father are one.””
“I and the Father are one.””
“I and the Father are one.”
I and the Father are one,[2] or one being, not one person, nor one by an union of affection only, but in nature, substance, power, and other perfections, as appears by the whole text: for Christ here tells them that none of his elect shall perish, because no one can snatch them out of his hands, no more than out of the hands of his Father: and then adds, that he and his Father are one, or have one equal power: and if their power, says St. Chrysostom, is the same, so is their substance. Christ adds, (ver. 38.) that the Father is in him, and he in the Father; which also shews an union of nature and substance, and not only of love and affection, especially when taken with other words of our Saviour Christ.

(2.) For what he argues—that you may know and believe, may believe it intelligently, and with an entire satisfaction, that the Father is in me and I in him; which is the same with what he had said (v. 30): I and my Father are one. The Father was so in the Son as that in him dwelt all the fulness of the Godhead, and it was by a divine power that he wrought his miracles; the Son was so in the Father as that he was perfectly acquainted with the whole of his mind, not by communication, but by consciousness, having lain in his bosom. This we must know; not know and explain (for we cannot by searching find it out to perfection), but know and believe it; acknowledging and adoring the depth, when we cannot find the bottom.
Verses 22-30 All who have any thing to say to Christ, may find him in the temple. Christ would make us to believe; we make ourselves doubt. The Jews understood his meaning, but could not form his words into a full charge against him. He described the gracious disposition and happy state of his sheep; they heard and believed his word, followed him as his faithful disciples, and none of them should perish; for the Son and the Father were one. Thus he was able to defend his sheep against all their enemies, which proves that he claimed Divine power and perfection equally with the Father.
