You're right, the UCC has been dead for a long time. I left a Congregational church in the early '80s because of it's ties to the UCC.
I am a member of a PCA (Presbyterian Church of America)church. I remember as a kid in the early 70's, my parents were involved in the forming of this new denomination out of the PCUS (Pres. Church of the United States). The main reason it was formed was because of the liberal stance that the PCUS was taking on abortion and other social issues. Since then, the PCUS has become more liberal. It makes me now wonder what they, and some of the other liberal-leaning church denominations, think about this social issue. I think I may do a little research on this.
