I am kinda surprised and confused by your reaction, but maybe that's where you're at in your healing process.
I mean, ceremonies are only meaningful if you let them be. If what they do is not meaningful to you then it's really nothing but a boring party with uncomfortable chairs and bad h'orderves.
My jw mother kinda freaked out once because a Wiccan friend of mine did a spell (or whatever it's called). I am a non-believer so why should it bother me when someone crushes up a leaf and throws it in the wind?
Who cares what rituals other people do? It has zero affect on your relationship with Jesus. But that's where you will probably be at eventually. I've been out for a long, long time.
