Should I go?

Gi

My stepdad wants to go to midnight mass tomorrow, but it’s not a Baptist thing so I don’t know if I should go,even though I want to see my step siblings and step nieces. Should I go? It’s a Roman Catholic, Lutheran, and Anglican thing. I want to go to see them, I am religious, but I’m Baptist would it be ok to go?.Step dad is catholic btw as is his whole family
