Of all the things Jesus said to get himself in trouble with the religious leaders of his day (“Your sins are forgiven”, “Before Moses was, I am”, “The Son of Man is Lord of the Sabbath”, etc.) what he said in John 10:30 might have been the topper.
ἐγὼ καὶ ὁ πατὴρ ἕν ἐσμεν.
I and the Father, we are one.
It’s a ridiculous thing to say… unless it’s true.
It was blasphemy for anyone to say that they were equal with the Father. The Father is God for goodness sake. How could Jesus possibly think that he ought to be thought of, seen, talked to, and experienced on the same level as the Father?
Did Jesus really expect those of his day to see him as the embodiment of the One they worshipped—the incarnation of Yahweh?
“You believe in God; believe also in me” (Jn 14:1, NIV)
It seems so.
