Concerning the prophet in John 1: 19-28
1) Do you believe this passage is authentic?
2) If it is authentic do you believe it was a part of the original Injeel?
3) If you believe that John's Gospel is simply a corruption but you are merely making a point from what you believe to be corrupted or fabricated material, are you not then wasting your time?
4) If you believe some words or phrases in the passage are authentic or even revelatory how do you differentiate between these and the fabricated part?
