Authority of instructions depends upon authority of instructor. But I do not cite authority of list. List has no authority in and of itself, but I say rather Jan wanted these things done. Danger is that authority of Scripture is easier to usurp than authority of Christ. False Christs, anti-Christs we can recognize.
False teachings are more difficult.
Go to Jesus. Jesus is the answer. He has all authority. He is the builder and owner of the church, church of Christ. He is the focus of our attention and allegiance.
