I would think that also Tintin, and normally it would be an issue for me, and at first it actually did bother me that they were so far doctrinally from what I understood, but they bring other things to the table... and though I live in a big city, home based Bible studies are not easy to come by that fit in my somewhat busy schedule. They consider themselves Christians: United Churchers and a couple of other denominations that may fall under that umbrella... apparently the United Church is apostate according to some. However I am learning to look for the similarities and not the differences, plus I learn so much from them, and they love me... as I do them. I love looking at and dissecting the Word of God with them, seeking understanding of what the texts are communicating, and seeing how others view it. I am always welcome to give my view as well. Sometimes I feel like I know so little and other times I can easily think, wow, God has blessed me with an abundance of understanding, but either way, I have had a great hunger and thirst for God's Word as well as experienced dry spells, and I much prefer the former. It is one of the places I get fed despite our differences.
Yes, the United Church of Canada is totally apostate. Many churches now have rainbow flags in the front in their sanctuary. I used to go to the United Church in the 1960's. I never learned anything about the Bible or God, after 3 years of going from age 9-11. By contrast, I went to Sunday School in a Baptist Church when I was much younger, age 5-8 and I still remember all the verses I learned, which came back to me when I was farthest from God. And influenced me not only in behaviour and ethics, but in wanting the peace of knowing God and being right before him through Jesus.
I have quite a few high school friends who consider this "their" denomination. When I mentioned something to them about a lot of fighting between the conservatives and the liberals, they said that was over and done with, since they got rid of all the "troublemakers!" Meaning the Bible believing Christians.
In the 1990's was when the liberals and the gay rights activists took power of that church. And yes, the Christians left, many going to the congregationalists and others becoming "community" churches. The sad thing is because the denomination actually owned the buildings, many local churches lost the building they had been in for over 100 years and had to start over.
I do agree with Tintin, that if they don't believe in the deity of Christ, they are simply NOT Christians. Unless you are there to spread the real gospel of Jesus, I think you are wasting you time, and also maybe being influenced for bad. I am glad you are seeking fellowship and want to study the Bible, but when you are with United Churches, you are going to get "another" gospel. That is all there is to it.
I don't know exactly where you live, but I would google Bible believing churches. There have to be some more conservative churches, who love God and study the Bible in your area. I also know you live in an extremely left wing part of the country, but that doesn't mean that you can't find pockets of people who do believe in the deity of Christ, and who do teach the truth of the gospel. (Regardless of their social politics!)
The big issue with the UCoC is that social politics has become the total gospel to them, rather than Jesus dying on the cross for our sins, and then we spread that gospel of love, which includes the works the Father gave us to do - like helping the poor, the broken and needy. Now that is a part of the gospel that much of the politically conservative Christians seem to have forgotten, but it is repeated over and over in both the Old and New Testaments.
