I did some reading into this subject, and discovered some disturbing things in the 8th century. If someone has further knowledge on Pope Adrian or Pope Leo III, I’d be interested to hear it. History is very important, especially to the Catholic Church and Orthodox Church, whom both claim to be the fulfillment of the Church of Christ on earth. I’m just glad to know that the apostolic sucession is recognized in both churches (the bishops being direct successors of the apostles). The claims of heresy about RCC teachings can’t be correct. That would undo many centuries and many beliefs that we hold today. I don’t know where I’m going with this but I’m not happy with what I read.
