The conversation is NOT about whether a doctrine is true or not! It is about Christianity being the only religion that has the Trinity doctrine.
It is not false. You are either deliberately not understanding what is being said in order to not actually address or accept what is said, or the problem is in comprehension. The Trinity is unique to Christianity. If that uniqueness is removed, what results has no legitimate claim to being Christian. They are basing their Christianity on something else. A Unitarian has the same belief regarding who Jesus is as to His person as the Muslim religion. Why not call yourself a Unitarian Muslim and add to that the belief that yeah, He did die for the forgiveness of my sins? Well whoops again. They don't believe He died for the forgiveness of sins so now you have still another oxymoron.
Unitarianism is its own unique religion with its own set doctrines.
It wasn't me who brought it up. It was
@Papa Smurf who asked the question of you and
@Soldier of Christ1516 about what were a Unitarian and Biblical Unitarian. I simply pointed out why there is no such thing.
They have already been given. Saying no, that is talking to Jesus not praying to Him, does not mean they weren't given.
That does not change the fact that the doctrine of the Trinity is exclusive to Christianity! Therefore, if that doctrine is absent in a religion, it falls outside of Christianity. Apostate from the Christian religion.
What exactly is it that makes you a Christian?
