I agree with the above posts that perhaps you should take a short vacation and get away from the intensity of this situation...
One way you can perhaps resolve some issues of this, is to sit write out your feelings and his as best you know them to be and then turn the tables.
Pretend that you are the one who has decided to make this change, what would you expect of him..what would you want for your family and what compromises would you be willing to make?? Looking at it from that perspective MIGHT help you to define what you are willing to compromise if anything and what you expect from him in return.
I have to be honest, from what I have heard on this board about this church...I would not want to be involved in it...
I actually have an uncle who also attends a church like that and during one of our conversations, we were talking about my mother who suffers from a mental disease (DID)...he says to me "you know she is full of demons..you have to pray for the demons to leave her"...to this day just thinking about those words makes me sick to my stomach...christianity is about love and acceptance and in my opinion logic...not about old day lingo that is being used to scare people have to death...(illness' were called demons in the bible because they believed that the people were demon possessed...obviously we know that to not be the case today...)
I think this kind of "religion" is negative and bad for the health of your family. Your children should not be hearing that their father thinks their mother is going to hell or that she is his "cross to bear"...and so on. And even though it might not be said in front of your children, the negative words are in the air...they are in your home, so they will influence your little ones.
Even as nice as the people might be, I would not want my children to be influenced by such negative energy and thoughts.
This is not christian behaviour and I would really try and come to a compromise (perhaps a non-denominational chapel or something) that allows him to practice some of his beliefs without them influencing you or your children...as the ones that he is presently practicing are so negative.
I am going to send good positive thoughts your way and encourage the horrible negative energy in our house to leave...
In my thoughts,
p.s. I am reading a book called The Power of Now by Eckhart Tolle...I have found it totally inspiring in my thinking about my Higher Power...I feel that with this book I can totally become connected...and I would assume that is the goal of every christian..this is not a bible based book..it's about achieving enlightenment...but I have really enjoyed the part about connecting with "Being"...just thought I would share that with you as you may try and look for compromises of some sort...
