my position is people should b free to follow Jesus how the spirit leads them, not be forced against their will to believe what a council tells them of fear of being burned alive.
if a group of murderers and destroyers wants to label me a heretic i am ok with it as i want nothing to do with those fruits.
There have been times when those who were "anathema" were killed, particularly by the Roman Catholics, but the Roman Catholic church did not have that type of power as a bishopric of Rome in the early years.
To be declared "anathema" meant being labeled as someone that Christians should not fellowship with, due to their heretical views, and the possibility of being contaminated by their false teachings. I have no issue with marking certain individuals in that manner..to clearly distinguish that they are stepping outside of the boundaries of Christianity. Denying the Trinity is one of those issues. Besides the doctrine of the Trinity itself, non-Trinitarians typically hold other heretical views. As an example, many Oneness Pentecostals teach that you 1) must speak in tongues to be assured you are saved 2) must be baptized in the name of Jesus only and 3) believe in baptismal regeneration. In essence they end up separating themselves from the body of Christ simply by their truth claims which exclude other believers.
I belonged to such a cult for over a decade..who similarly declared themselves to be the "true faith".
By the way, I find it hilarious how cultic individuals view themselves as being the poor persecuted group, whereas they constantly engage in condemning Christianity because Christianity teaches against their position. The alleged "poor persecuted group" actually engages in rock-throwing and declares Christianity to be the ones with the problem.
I found it liberating to give up the paranoid mentality that the cult caused me to have toward Christians. And after I associated with real Christians, I realized that the lies the cult told me about them (that they were ignorant and unsaved) were just that..lies.
So, keep painting yourself as the "valiant defender of the truth"...that's usually how heretics like anti-Trinitarians view themselves.
