I think the thing that hooked me was the Sunday school class. It gave me an open invitation to express my opinion and join in the conversation. In the Assembly Church, both the Sunday school classes I attended were lecture format with very little student participation.
I didn't take notes on the sermons, but I think the Assembly sermons may have been more in depth and challenging. I guess time will tell. I do want to try St. Mark's United Methodist Church again. I like the Sunday school class and I can deal with the sermons for a while. Maybe I'll do more reading and writing. This is part of my adjustment to my new life. Check back in a few weeks to see what I decide.
