Humans have no problem holding in their mind simultaneously two fundamentally opposing ideas. Your question stems from the assumption that beliefs and especially religious ones are borne from this sort of unimpeachable internal logic, if A then B. That’s enlightenment wannabe thinking how we should be. And it isn’t like that.
Also, we are herd animals, we want to belong to something. A lot of people want to belong to this or that religious group to fulfill their own needs. Even if they disagree with some of the religious commandments. So they espouse stuff they don’t actually agree with without any or much internal conflict.
I also feel that few people are actually “raised Christians.” They tend to be raised Baptists, Presbyterians, Catholics, Mormons, etc. They have wildly differing views on that carpenter from the Middle East and what it all means.



I’d argue he isn’t a great leader; he is a successful one. He gambles, he takes chances, and is swashbucklingly lucky throughout his career, even when he gets punished, until he meets and follows the lead of arguably the better leader between the two of them, Jean-Luc Picard, in the nexus.
TOS was quite woke in its day. There is still an awful lot of sexism on that Enterprise. The treatment of Spock is quite discriminatory. You could argue his unilateral decision that appears to be salomonic more than covered by actual law or regulations to maroon Khan and company on Ceti-Alpha 5 leads directly to the death of his own son, of whose existence he didn’t really know because his mom knew better than to stay in Kirk’s orbit. While you could say that an orderly private life isn’t a prerequisite to being a great leader, I think Carol Marcus knew he’d be trouble at home and at work and that’s why she wanted out.
He was very often in the right place at the right time and only made decisions that were later judged not to be entirely wrong. He had the charisma of a great man right until he oh-my’ed loose his mortal coil. If there had been an HR department between the music room and the colorful food cube dispensary there would have been need for the admiralty to get involved. He is a beloved character for his brazenness and faults.
