Forgive your enemy and turn the other cheek, doesn't strike me as militant.
Not rebelling and preaching against rebellion is not militant.
Even on the issue of slavery, as discussed many times, they were NOT militant, on the issue of serving Roman they were not militant, in fact, I don't recall any passage that advocated rebellion or militant action.
I may be wrong, but I don't recall any.
May I shift your focus off that word "militant"?
Rome had the most awesomely ferocious military and secular police forces in history!
It was unthinkable that christians should react in any way "militant".
What I'm referring to is between the sects of early christian doctrinal disputes.
One set of christians would beat the crap out of other christians all too frequently.
Tolerance was never a strong suit when it came to orthodoxy. Especially among judeo-christians.
Remember, the Old Testament God had wrought a nation of "thought crimes" punishable by death.
Jews had been commanded to stone to death their wife, son, daughter, best friend WITHOUT MERCY if they worshipped (non-existent) false gods.
When these self-same monomanical jews accepted Jesus as Messiah their views of purity and orthodoxy did not change!
Do you think a Monotheist Christian/Jew looked kindly upon a Trinitarian christian congregation spreading the idea that Jehovah was really 3 Gods (in one)?
There were riots, murders, violence, mayhem and unrest all throughout the sectarian overlap of competing christian congregations.
