Oh absolutely, you’re right here and you’re right in your first comment, it is a fundamental belief of 99.99% of mainstream Christianity

Just personally, as someone who came to see the Treasures contained within Christianity later in life through attempts to logically grapple with it (as opposed to being born into a sect of the faith), I look back at this oldest of schisms which still festers today in many ways:

Given the choice between defining Christianity as “choosing to act like Christ” (as revealed in the Gospels and associated texts), and defining Christianity as “choosing to believe that God and Jesus are Father and Son/part of a Trinity/etc”, I see the latter as having so much unnecessary suffering associated with it through the last 2000 years of bloodshed that I can’t reconcile it with the first.

For example, how many “Christians” today use their interpretation (foisted onto them it may be) of their faith to justify support for israel, a modern day genocidal state which embodies much of what Hitler apparently believed, just with the roles reversed? A disturbing amount by my estimation. Stuff like that leads me to think “huh, maybe the mainstream answer in this realm is just as wrong as the mainstream answers in every other realm of investigation, maybe I should look deeper into these older conversations and debates, see who made more sense.”
