Denying that God is triune puts you outside orthodox Christian teaching?

Okay. I think it is extremely arrogant of people to think their understanding is above the counsel of the Church throughout history and their personal opinion trumps the collective wisdom of saints.

And you are outside orthodoxy, which has been my only point. I am not interested in getting you to change your perspective, just be honest about what it is.

Liam pointed you to scholarship on the dating and origin of the Apostles’ Creed and the Nicene Creed which reflects what I learned in church history and systematic theology classes. You did not respond to that, so you are actually the one disagreeing without evidence.
