Sola Scriptura Man: I go by the Bible alone. I am my own authority in interpreting the Bible also!
Tertullian: "By what authority, pray? Prove it. If you are a prophet, predict something. If you are an apostle, preach in public. If you are an apostolic man, agree with the Apostles. If you are an ordinary Christian, believe what has been handed down. If you are none of the above, then, with good reason I say: Drop dead! For you are already dead, you who are no Christian, not accepting the faith that makes us Christians....What was handed down was true as it was handed down by those commissioned to do so. Thus, by rejecting what was handed down, you have rejected the truth. You had no right to do that."
