Fritz, I don't want to put words in your mouths, or thoughts in your heads, but I think you and your dh have fallen into very natural and understandable ways of thinking about your new situation. The question will be, can you get out of this and find a way to live together happily?
From your point of view, your dh has moved the goal posts. When you met, you agreed - you were both atheists, and everything was fine. Now he's totally changed, believes something which you consider nonsense, and he would like you to give it a try, or at least come along with him sometimes. Why should you compromise? He's the one who has changed! You are hurt that his new interest takes up family time, and that he thinks you are 'lacking' in something now.
From his point of view, he's discovered something that has changed the way he looks at life (for the better), and he thinks you would be happier if you found it too! Or at least if you understood what he now believes. Effectively, he thinks he was wrong before, and that he should persuade you to change your mind. He's hurt that you are not interested.
I don't think it's wrong for either of you to be hurt. Feelings are just that - feelings. The question is, what do you want to happen?
I would guess that you would like him to give it all up and go back to being the man he was before, while he would like you to become a Christian and join in with his new life. Neither of you are going to get all of what you want.
So you both need to compromise, or this relationship is doomed. Maybe you would rather walk away than compromise - and that's your choice of course.
But if you both want to carry on, you need to have some practical ideas. It's not about persuading each other of the rightness of your view, it's about living together without falling out.
Could you try some of these ideas?
Maybe you all go to church once a month. In between times, some weeks he goes alone, some weeks you all go out and do something else (non religious). No one sulks when it's not 'their' week. You try to appreciate the efforts the other is making to compromise.
You agree not to try to persuade each other of the rightness of your views for a period of time (a few weeks or months?) to let things cool a bit.
You both try to find some other couples who make this work - and ask them how they do it. Focus on what you do have in common rather than the differences. Take some practical advice. Try not to focus on who is being more or less tolerant.
All this is easier said than done. I've been in a relationship like this, and it was hard. It's a lot better now. I don't think we were as entrenched as you both are, perhaps, but not far off. All I can advise is to remember it's not about winning the argument. You might win, or he might, but find yourselves alone. That would be a shame if you could stay together and both be happy, but to do that you have to stop wanting to change each other's minds.
