You can't be a Christian and not believe in the Trinity- as it is the Godhead of Christianity.
There's no debating it- take notice to the other things non-trinitarian churches teach. They are heretical and at best teach a cheap version of Christianity.
There's Islam if you think Jesus is just a glorified subordinate of God :idunno:
You can't have it both ways though, that does not suffice.
The Apostles were not Trinity belivers. Your church has added many things to what the first church believed in.
