Just making the comparison terycarl. All false religions rely on something other than scripture alone. Something added. Additional revelation. A new apparition. Each one looks to something that isn’t found in scripture or that wasn’t taught by the apostles. The list of those that do that includes Catholics, Mormons, and Muslims.
Nonsense and ahistorical. If true, then the Hebrews would have been right to reject Moses. The Bible is one long continuing revelation and nothing in the Bible definitively states nor can be construed to imply that revelation will end. Quite the opposite.
Christ tells Peter to expect continuing revelation. It comes, most notably via his trance revealing the time to take the Gospel to the gentiles. Look at the same chapter in Acts 10 for Cornelius's experience.
Cornelius' prayers and offerings are acceptable to God. An angel comes to speak to him. Does anyone still read the Bible or do they just stake out a position based on a few snippets?
A person who wants to be a Christian, a follower of Christ, should absolutely expect continuing revelation, angels, ordination, baptism and an organized, orderly church.
