I was the Christian in our relationship - not the zealous kind, I believe in pubs as much as I believe in God. My husband was more agnostic. I made it clear from the outset that I wanted our kids to be brought up in the Christian faith, which he was absolutely fine with - he knew what I was when he met me, so it didn't come as a surprise.
We came to a compromise - the kids and I went to church on Sundays, came home, and we'd do family stuff. He'd occasionally go to church and we'd then spend the afternoons at my mum's, or we'd miss church altogether and spend the day at his parents. We never celebrated Halloween, not from a religious point of view, but were both of the mindset that sending your kids out to take sweets from strangers is just a little weird, especially having grown up during the Stranger Danger era, although he would carve the odd pumpkin now and again.
You need to sit your husband down and get him to understand that having faith is great, but restricting what his children (and indeed wife) can and can't do for religious reasons is only making a rod for his own back when it comes to their later years. If he makes alcohol and pubs a no-go zone, guess what, the kids will make beeline for them when they are older. I'm assuming he's of the mindset that the man is the head of the household, hence the "I'm the man, I make all the decisions" stance? I suggest he reads Proverbs 1:5:
A wise man will hear and increase in learning,
And a man of understanding will acquire wise counsel
Maybe he needs to speak to his Pastor/Vicar/whatever, as to what that actually means from a biblical sense, because it sure as hell does not mean his wife should shut up and put up! Biblicaly, husbands should respect their wives, that means taking on board your thoughts, opinions, wishes, etc.
If all of that fails, then I'd be making plans to leave, as you'll be setting yourself and your kids up for a lifetime of control and disappointment otherwise.
