I am asking you to define what this “Church” is and how it is separate from the humans in it. Do I need to try to rephrase the question? You seem to be repeating that you believe it is infallible because Jesus started it. I know that Jesus started it. I am asking what that has to do with the fact that Jesus then immediately died and this worship immediately became a congregation (church) of fallible men and women. Whether there is a God or not, how is/was this congregation infallible? Other than as an idea?
Jesus not only started it and gave it authority, through His own authority, He promised to be with it until the consummation of the world. He spoke those words to ‘mortal’ men and He knew they would die eventually but, that His Church would continue until the consummation of the world. By Christ’s promises, the Church is infallible.
