I've seen plenty of ruthless debates on YouTube of non-believers literally destroy the opposing defending "faither" on claims of morality. And since I cannot find solid grounds to believe that it is the case: morality is created through religion, Please provide some enlightenment to my membrane and, so-to-say, persuade me as to why you're right.
It not some specific and coherent moral philosophy.
It is based on 1) the Ten Commandments and 2) the actions of the characters through the Bible (David, Elijah, Jesus, the disciples, etc.) The thinking is that if these are holy men and if what they did is considered good by God, then those are the type of actions that people should do. These moral actions are sometimes explicit as in the letters from the apostles in the New Testament or implicit in interpreting the actions of people in the books.
