I don’t know how any of that refutes what 1 Tim 2.5 plainly says: there is one God and one mediator between God and men, the man Jesus Christ. Jesus is therefore distinguished from the one God. This is totally incompatible with the Trinity. I know in many discussions there is merit on both sides and reasonable argument can be had. But I don’t think this is such as case. If it wasn’t for centuries of dogma, the prestige of the church, and the stigmatisation of JW theology as heretical, I don’t think the discussion would even get off the ground. The Bible tells us dozens of times that Jesus is separate from and distinguished from God. Dealing with the inventive ways Trinitarians come up with discounting each and every one is simply a waste of time.
Good video on some of the places Jesus said he wasn’t God here.
