No. He was praying to God the Father, to the Frist Perosn of the Holy Trinity, not to divine nature, just as He was calling on the Spirit, the Third Person of the Holy Trnity, and not on divine nature.
When He says He and the Father are one, He means in essence (nature), i.e. divine, not in Person.

How do we DISTINGUISH the three persons from the one divine nature? I ask because I have some experience in this area and the results were most unfortunate for me! LOL!
Under what you say above, would it be equally proper for the Father to pray to the Spirit, or for the Spirit to pray to the Father, or for either to pray to Christ? Is first, second, third "person" an order of importance?
