I’m reposting my response from a journal entry:
A United Church of Christ church was a haven to me in my teenage years, after having to deal with a much more strict church while growing up. My parents went to this previous church, a Dutch Reformed (Calvinist) one, because that was the denomination they were raised as, and it was what they knew. A lot of their teachings, including the fire-and-brimstone preaching and the heavy emphasis on predestination, really messed with my young head. Instead of listening, I read the Bible through a number of times, seeking to escape the sermons. I think finally the Mother’s Day and Father’s Day sermons (women belong in the home, wives should be subservient to their husbands) finally got to my sister and I enough where we protested to our parents, and this time they listened. They were very liberal considering their upbringing, and agreed with our complaint.
We checked out a UCC church that I’d become familiar with through friends of mine. They’d invited me along on summer “field trips”, checking out things like the University of Chicago’s museum of Middle Eastern artifacts (to see the history of the region represented in the Bible), or the gorgeous Ba’hai temple in a Chicago suburb, both for the architecture and the religious knowledge. I was thrilled at the difference. My old church debated the concept of allowing women to become deacons in the church - it was quite controversial to them. This new denomination, I learned, not only had women pastors, but also gay and lesbian pastors - homosexuality was condemned as a sin in my old church, using the Sodom and Gomorrah story improperly as many Christian churches do. They also will perform commitment ceremonies for gay and lesbian couples. (IIRC, they do not condemn abortion, though I could be wrong on that.) A hymn that we sung one Sunday rather poetically taught that evolution and the Big Bang and all that happened, but that God essentially triggered the Big Bang. Mostly, it was a more warm and loving place, one that rather than condemning humanity for sinfulness, tried to provide gentle guidance through an imperfect world for imperfect people.
It is an extremely tolerant and open denomination. Like all organizations, this may vary between locations, of course. I’ve seen a number of friends weigh UCC vs. Unitarian Universalism, as both have reputations for openness. Typically their decision hinges on whether they still consider themselves Christian or not, as UCC is a Christian church while UU is more of a (from what I’ve seen, I’m not UU) philosophy group.
I’ve attended sermons at UCC churches only sporadically over recent years, but it was enough for my Catholicism-dissatisfied husband to speak favorably of the church and consider attending more frequently, even joining.
