Christian opinion of Chinese superstition

Everyone comes with their own culture whether it's Chinese, Texan, Christian, or whatever. Your FMIL expressed a wish for it not be in April. She probably is also expecting an inside wedding where weather doesn't matter. You can go against her wishes if that works for you. But, it's not the wrath of God, but the disappointment of your FMIL. Ask your partner what they think about an outside April wedding in TX? Also, you don't have a date until a venue confirms their availability so try not to put the cart before the horse.

It could be good to avoid April if your FMIL would be strongly sensitized to her superstition. In any difficult situations she might raise that month as part of a rant (if she might ever have that sort of attitude). Otherwise, it might be like avoiding cracks on the sidewalk; sometimes you might do that but most of the time you don't check and don't care.

So, just get a sense how big an issue this is. You benefit from having full family enthusiasm and support.

Every culture and religion has superstitions. Most Western superstitions you’re familiar with come out of Christian beliefs — walking under a ladder breaks a triangle, symbol of the Trinity; Friday the 13th comes in part from the Last Supper and several other Christian events, etc. So don’t insult your FMIL just because she has a superstition you don’t share. No, nothing will probably happen if you schedule it in April . . . except your FMIL will remember that you dismissed and denigrated her beliefs. Ultimately you and your fiancé are the ones who get to choose the date. But your marriage will be longer than a wedding day, and so will your relationship with her. So think about how important it is to you and to her, and if you end up choosing an April date at least come up with a nicer way to tell her than “your superstition is stupid so we’re ignoring it.”

From a Christian perspective, no, superstitions are not actually part of our belief system. It's not one of the commandments to avoid getting married in April. At the same time, it is a commandment to honor your parents, so you could avoid April as a sign of respect for your FMIL. One thing that you want to be mindful of is whether there are superstitions in your own family that you are subscribing to, like are you going to have something old, new, borrowed, or blue? If so, then it might come across oddly if you follow your superstitions but not FMIL's.

Ha, that's funny when I'm one of the nicer posts. But, yes like the PP's write, you should learn how to respect your FMIL instead of othering her and calling on close-minded Christians to support you in calling her a bad Christian, worthy of ridicule. I'd learn this ASAP before your partner cancels a future with you and there's nothing to plan.
