A very concise but educational video describing how the biblical canon was formed and the differences between the choice of scriptures that some of the major Christian schools of thought follow.
It also details the evolution of Christianity from Judaism and compares some of the similar and disimilar scriptures between the two religions. There’s some good bits of history thrown in for good measure as well in the video. I just found this channel recently but I think with the quality of the info and video I may be highlighting some of his content in the future, a link to his channel is below if you care to follow him.
