purpose, yes. But he obviously was
not saying that he and the Father were identical.
Otherwise, Jesus would have been telling his mother, on the occasion of him confounding the elders in the temple, that he must be about his own work...
Would have been telling his Apostles, when they asked how to pray, that they should pray to
him, saying
"Our Father, who art here, hallowed be my name" etc...
Would have been praying to himself in the Garden of Gethsemane that he should take away his coming arrest, torture, and death by himself...
Would have been asking himself, on the cross, why he had forsaken himself...
Its all too obvious.
