actually rules about religion discussions are strict on chess.com
https://www.chess.com/legal/community refer this . and i would suggest before posting any religious discussion or blog on chess.com discuss the content in it with some mod or staff so that you know you are on safer side .
apart from that clubs about religion are exception but any religious debate can be violation of guidelines .
hope this helps
Can we mix religion into chess clubs or on profile blog post I want to know because I want to try it out and make a religious blog posts
