The Principle of Infallibility

The book of Acts gives us a clear example of what this looks like in Acts chapter 15, right? At this famous apostolic synod in Jerusalem, all of the Lord's core apostles were present. They all ruled that Gentile Christians are not bound to keep all the precepts of the Mosaic law and said that this quote seemed good to the Holy Spirit and to us. Now this creates a principle that I believe allows us to be infallibly certain of the historic New Testament canon.
