NTA. You have free will, don't let yourself be pressured into going somewhere you don't want to go, especially if you've already talked to him about it. That is not your religion and you are not held responsible for attending any events associated with it, so it's completely valid that it's not something you're comfortable going to.

Frankly, it depends on how important this is to him. You’re NTA for being atheist, but you ATA for not going to something he may find value in doing. Sometimes it’s about stepping up for your partner, even when the situation is uncomfortable.

Nothing wrong with not being religious but if you aren’t willing to go to a church service once a year, why are you with him?
