10:30,31 I and [my] Father are one. Are so united that the Father is pledged to keep the sheep of the Son. These words the Jews held to be blasphemy, and sought to stone him. Compare 8:52.
10:30 I and the Father are one - Not by consent of will only, but by unity of power, and consequently of nature. Are - This word confutes Sabellius, proving the plurality of persons: one - This word confutes Arius, proving the unity of nature in God. Never did any prophet before, from the beginning of the world, use any one expression of himself, which could possibly be so interpreted as this and other expressions were, by all that heard our Lord speak. Therefore if he was not God he must have been the vilest of men.
10:22-30 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.
