The earliest foundations of Christianity, when proto-Christians met in councils in Mediterranean cities to argue about doctrine and which pieces of writing would make up what became the New Testament canon, were defined or characterized by extreme violence, up to and including many murders.
The doctrine of the Trinity wasn’t settled on until many proto-Christian thinkers had been clubbed or stabbed to death by the paid gladiators of other proto-Christian thinkers.
This is not a secret. Every biblical scholar and Christian historian in the world knows this.
It’s something all of us probably should be talking about much more than we actually do.
