The United Church of Christ is a very liberal group. I am posting a text from Wikipedia which shows they believe in gay rights and abortion in some of there churches.
“The UCC maintains full communion with other mainline Protestant denominations, while many congregations choose to practice open communion.[4] The denomination places high emphasis on participation in worldwide interfaith and ecumenical efforts.[5][6] The national settings of the UCC have historically favored liberal views on social issues, such as civil rights, gay rights, women’s rights and abortion rights. However, United Church of Christ congregations are independent in matters of doctrine and ministry and may not necessarily support the national body’s theological or moral stances. It is self-described as “an extremely pluralistic and diverse denomination”.[7]
Not much of a conversion if he just joined the UCC afterward.
