One elemental aspect is your disbelief in the Trinity. All Christians confess this to be true.
There are also several blasphemous teachings in the Mormon church which exclude by default.
What does that mean?
“All” Christians confess this to be true? That’s simply a way of saying, “Hey, MOST of us have decided that this is what theat verse means, and there are more of us that think this way, so majority wins, we’re right and you’re heretics.”
And “ALL” Christians have most definitely NOT believed the man-made Trinity doctrine.
Saint Justin Martyr saw Christ as “a second God, second numerically but not in will”—that is not “orthodox” trinitarian dogma.
Eusebius of Caesarea, the “Father of Church History,” signed the Nicene document, yet he was a subordinationist who maintained that “everyone must admit the Father is prior to and pre-exists the Son.” That is not “orthodox” trinitarian dogma, either.
Were Eusebius and Saint Justin Martyr Christians?
