I appreciated reading your experience TimothyT and want to encourage you to keep on searching. I think troubled mind and Band On The Run both had some good thoughts and suggestions for you and Jack to follow.
My experiences at the Metropolitan Community Church of the Rockies continue to be positive. The entire service lasts for an hour and while there is singing and praying the pastor's "message" (as they like to call the sermon) is definitely Bible-based. Two passages are the theme texts on which the sermon is based. Yesterday the selected passages were Isaiah 45:1-7 and Matthew 22:15-21. I like the fact that all of the Bible is considered at MCCR and not the New Testament only. I am now working on getting to know people and make friends there but I'm sure I will succeed. I'd invite you and Jack to come worship with us, but you might find the trip from Nottinghamshire to Colorado difficult to negotiate on a Sunday!
At least you both were given a warm welcome and that means a lot, but obviously you want more. You are seeking to fill a spiritual need and that is equally important in my view. I have to believe there is a church near you that can be warm, loving, accepting and Bible-based which will give you what you want if this church does not. But give the Nottingham church a little longer. Also, speak to the pastors about your concerns and see what they say about the church's philosophy in addressing them. Move on if things can't be worked out.
