SEV Biblia, Chapter 10:30
Yo y el Padre una cosa somos.
Clarke's Bible Commentary - John 10:30
Verse 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, egw kai o pathr en esmen-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 chap. xvii. 11, 22.
Matthew Henry Commentary
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 Jew understood his meaning, but could not form his words into a full charg 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 perfectio equally with the Father.
