If I can put it this way, modern psychology and Christianity are two ways of looking at the world. There are going to be a few conflicts.
My T has known from the start that from time to time, I check in with my pastor on how it's going, and I have needed to get his clarification on a few things for which he has insight into and she has not. So far, they have only disagreed twice.
He did take an extended travel, though, and in his absence something came up that T could not answer. I have a friend living far away, whose whose DH is a PhD psychologist of my own faith; we exchanged some email.
I told T that I was in process of asking him, and also shared his reply with her. She seemed very much OK that I'd done it, no problems,.
