Adam Clarke on John 10:30

I and my Father are one - If Jesus Christ were not God, could he have said these words without being guilty of blasphemy? It is worthy of remark that Christ does not say, I and My Father, which my our translation very improperly supplies, and which in this place would have conveyed a widely different meaning: for then it would imply that the human nature of Christ, of which alone, I conceive, God is ever said to be the Father in Scripture, was equal to the Most High: but he says, speaking then as God over all, I and The Father, εγω και ὁ πατηρ ἑν εσμεν - the Creator of all things, the Judge of all men, the Father of the spirits of all flesh - are One, One in nature, One in all the attributes of Godhead, and One in all the operations of those attributes: and so it is evident the Jews understood him. See Joh 17:11, Joh 17:22.
