I was generally comfortable in my home church, a small, friendly congregation (United Methodist). I was confirmed there and joined the choir.
My husband is Catholic and since we married 3 years ago I have been attending Mass with him. At first, it was like stepping into a different country (though, ironically, my mother's family had been Catholic for years before having a falling-out with the church back in the early 20th century over a baby dying and being buried in 'hell's corner' of a cemetery (the "limbo" thing). Long story. Anyway, I appreciate the formality and sacramental nature of the Mass...at my home church, my pastor is into congregation-participation rituals and exercises...kind of "new-agey" stuff that makes me at times uncomfortable, like I'm making a spectacle of myself...it's the sort of stuff that belongs to spiritual retreats but not necessarily in actual church services, in my opinion.
