Protestants and Catholics both believe in One God in Three Persons, Father, Son and Holy Spirit. If you don’t agree with who God is, you will never be considered Christian.
Would engaging in murder and torture disqualify people from being considered Christian? Or perhaps giving their approval and support to those who do?
Sorry, but Christ didn’t even believe in the Trinity. Christ himself declares that God the Father is his own God just like the he is Almighty God to each of us in John 17:10. Another obvious example is when Christ died on the cross and commended his spirit into the hands of the Father.
If the Trinity is so essential to Christianity ... then why did it have to be established by an Emperor in 325 and by a murderous purge in 380-400 AD by Theodosius II? Also .... why can’t it be proven by the bible alone without relying on the Creeds?
More recently, during the “First Vision” in 1830, Christ himself declared to Joseph Smith that the various Creeds were an abomination in his sight.
In other words .... the whole “three in one ... one in three ... but not always three ... and not always one ... and three incarnates ... but one incarnate .... but sometimes three incarnate” ..... Never was endorsed or taught by Christ himself!
Grig, simple concepts. You're simply, completely wrong.
