Dear flee,
I will echo Easter Joy’s concerns about the raising of children. Please do not take our word for it (again, even though I personally have considerable experience with mixed marriages). Just read any of the literature out there – not just Catholic – about “mixed” marriages. (Reiterating what others have said, your fiance is not an ex-Catholic or a non-Catholic; he is a non-practicing baptized Catholic in opposition to the Church. Technically this is not a mixed marriage, but it has all the appearances of a mixed marriage where one spouse is uncooperative.). The real crisis emerges, even if suppressed prior to this, when children come into this union, not necessarily during the pregnancy but definitely after the birth.
Let’s pretend that your husband’s negativity will have zero impact on your differently positive faith. Let’s pretend that you have a parallel reality alongside your marital union, which is your faith and your unhesitant, unapologetic attitude toward affirming it and practicing it, and that your husband’s negativity does not affect you. (Quite a stretch, but I’ll give you the benefit of the doubt here. The suggestion is also problematic on its face, because of everything a Catholic marital union implies.)
That accepted, into the world comes Baby #1. Believe that there will then be a struggle, as there is for mixed marriages across the country, and over decades, about the raising of the child. Presuming you are still following your faith fervently at that time, you will not be content not to baptize and educate your child in your faith. And (sometimes, as you can read in the secular literature, including with couples neither of whom are Catholic) this tension will overflow especially into the extended families. If anything, in-laws are even more invested in the raising of the child in one of their traditions. If your family and you want the child baptized, and hubby and/or his family does not, this will be a major point of conflict between the two of you.
In fact, the birth of a child, to a non-practicing Catholic couple (where both have not been practicing) often triggers a crisis of faith or realization or reversion in one/both of them. That’s fine if the reversion or new enthusiasm is joint, but it’s taking a huge gamble if we’re talking not about lukewarmness or apathy but outright opposition/dislike of the Church, on the part of one partner.
The easiest time for a person to learn any faith is as a young child, going forward from there. That is when faith is most easily and most logically planted. Young children are receptive and intuitive, with heavy right-brain consciousness at work, promoting that faith. The literature out there about the misguided couples who “wait” or who “let the [grown] children decide” about religion shows terrible statistics for this group. Overwhelmingy, the children “choose nothing.” They are left with no intuitive sense of the divine, and without an intimate relationship with God. Yes, there are exceptions. Some of these are on CAF. But those are definitely the minority.
One of the saddest examples of all is the widely publicized example of Dr. Laura Schlesinger. She was raised as a non-practicing (“cultural”) Jew. She was determined not to repeat that for her own family. So when she had her son, she provided the whole megillah, so to speak. Further, she was deeply steeped in Orthodox practice, with women separately seated in temple, etc., with long services on Shabbat & High Holy Days, with strict observance of kosher laws. Her son’s Bar-Mitzvah occurred in Israel.
Then, when she was on Larry King (I think?) one night, she sobbed openly, when asked, about her own relationship with God and her own feelings about – not intellectual commitment to --Judaism. She admitted that all that effort with her son provided him with an organic relationship to God, but that she, Laura, is unable to pray, unable to “connect” with God, regardless of all her effort with her own son and her own ‘reversion.’ She has, she said, tragically accepted it, and it is a great pain in her life. She has resigned herself to having no personal relationship with God.
Please think about how important it is to get your fiance’s explicit (again, I would suggest in the company of a priest and/or Catholic therapist) agreement not to express or show, ever, in the presence of your children, any attitude toward the Church, your child’s education, your own religious practice, that conflicts with the child’s formation in the faith. Naturally it would be better if he showed open enthusiasm, but the former would be the least that would have to be expected in order for your children not to feel conflicted or cynical about their faith. It’s tough enough with today’s societal influences to raise a commitedly religious person, of any faith.
