Curious what Christian theologians or the Bible may have said about this. It seems like Jesus speaks in terms of his father's will as if it is not quite his own, which suggests separate minded-ness. And what of the Holy Spirit ? Is the Holy Spirit thought to have a mind in the same way Jesus and God the father are thought to (since they are considered "persons" in some sense of the word). Maybe there are ways it could be a bit of both shared and separate. There may be no obvious answer on this and it could be just up for speculation, and if so, I'd be interested in learning that fact at least.

Normally I would hear the answer is one mind, but I was wondering; If beliefs are part of your mind, and since Jesus (the second person) would believe "I am the Son of God" and the Father would believe "I am the Father", They would believe two different things i.e, The Son would not believe He is the Father but the Father would believe He is the Father. Shouldn't that mean the Trinity should have three minds (for each conciseness/person) and one will?
