[AOII Angel]

All I have to say is it's not church. You aren't there to worship. As pshsx1 says, there is a difference between preaching and explaining the source of an organization's values. I doubt very seriously any group has a ritual that includes offensive material, but sourced material from the Bible or other religious texts may be uncomfortable for some members. We have discussed before whether fraternities required members to take an oath that they were Christians or believed in God. The same may occur in sororities. Individual conscience decides whether or not someone who does not believe in God or a member of another religion could make that oath without discomfort.
