tri delt methodist?

Hi. Obviously I’m following all the Greek accounts bc I’m about to go through and have a few friends or acquaintances in each house. I saw several posts of all the Tri delts going to Methodist service together? Is their required of all members in their hour or just optional? I am catholic and I don’t think I would feel comfortable being forced to attend a church service that is not my denomination. I’m all for people knowing Jesus, but this is a very personal relationship for me. I just don’t want to feel pressured.

Is this common in other houses?
