Is this a good sign?

My estranged parents finally agreed that we need counseling, but they’re only willing to go see a Biblical counselor. “That should be the only acceptable form of counseling”, according to my father.

On one hand, counseling is still a step forward towards repairing our relationship. On the other hand, they dismissed my concern that the definition of “Biblical counseling” could vary widely depending on the counselor’s interpretation of the Bible.

My parents and I are all Christians, but I go to an LGBTQ+ inclusive, affirming church, and they go to a church that is way more American evangelical and “fundie”. Our spirituality differs wildly, and the counselor will be a recommendation from a close friend of theirs who is also a Biblical counselor.

I’m probably overthinking it, but does anyone else here have experience with Bible-based family counseling?
