My father in law is Catholic and my mother in law is, well, we don't really know but thanks to people on this site, they say she believes in "new religion." For years, she appeased him and went to mass with him. But she finally had enough and now he goes by himself. That works for them. Her husband is grown up enough to realize they have to agree to disagree. For their everyday lives, their differing beliefs are not an issue as there are many more important aspects to a marriage besides if you believe in sky daddy or not (i.e, how you handle finances, your children, how you treat each other, sex life, etc...).
I would have a long talk with him and tell him that you will not try to impose your atheism on him if he agrees to not impose his Christianity on you. He can go to church by himself.
