A repeated gesture can preserve connection without requiring every old belief to travel with it.

Practices and the beliefs behind them can come apart. Lighting a candle, keeping a Sunday meal, saying the same words at the same time of year: these can hold a family together even when the people doing them no longer agree about what any of it means. The gesture is the thread, and the thread does not require unanimity. Demanding full agreement before anyone may take part tends to end a practice rather than purify it.

If a family ritual has stopped matching what you believe, you can keep the part that keeps you close. Turn up, do the gesture, and let the rest stay quiet.
