OT is rather... authoritarian.
I was a member for 20 years, left after high priest abused kids (church covered it up for years, he is now in jail).
Let me warn you about "the spirit", elevation emotion is real, but it is not from God- see examples of it in heaven's gate etc
Humans are herd animals, we seek to belong to groups. Authoritarian type groups with dictators / Nazi / prophet tend to be very dangerous.
The best groups are "by the people", democracy, encourage free thought, humble- admit when they are wrong.
Find a good group - non-denominational, no dogma tend to be best.
