We need to be quite weary of these “Christian” churches that are actually trojan horses for islam.
The United Church of Christ is not the same denomination as the independent “churches of Christ” that you see scattered throughout the midwest.
The UCC is probably the most ultra-liberal of the organized denominations in our country. It is just a step behind the unitarian-universalists who threw Jesus overboard generations ago.
The UCC affirms every sort of relationship that the bible warns against. It teaches a “mythical” Jesus in its seminaries.
It rejects the validity of most scripture and redefines faith and salvation. It is little more than a political institution, preaching a social gospel and not an eternal Good News of a bodily resurrected Savior.
My denomination (Methodist) has had leaders attempting to take methodism down that same road, but the grass roots have mightily resisted and are being heard.
I would never recommend a person join the UCC.
