What follows are quotes from prominent non-Catholic writers, speakers and scholars who, although they don’t accept the Papacy, admit that Peter was clearly the leader of the Apostles and/or that he had a primacy of some form. Of course, it is foolish and heretical for them to deny Catholic teaching on the Papacy; for if Peter was the leader of the Apostles based on passages such as Mt. 16:18-19 and John 21:15-17 (which clearly deal with the conferral of authority), then obviously Jesus intended to establish an authoritative position that would continue after Peter’s death. Nevertheless, such admissions show that St. Peter’s primacy is obvious in the New Testament, and they should point people to the truth of the Papacy. This file will be updated as time permits.
Walter Bauer (Non-Catholic), A Greek-English Lexicon Of The New Testament, on Πέτρος, p. 809: “… Peter, surname of the head of the circle of Twelve Disciples, whose name was originally Simon.” (BDAG, University of Chicago Press, 2000)
Bauer (1877-1960) was one of the producers of the famous Greek-English Lexicon known as BDAG, which is considered “among the most highly respected dictionaries of biblical Greek”.
D.A. Carson (Protestant), The Gospel According To John, 1991, p. 678: “Matthew 16:13-20 certainly establishes a unique role for Peter in the founding of the church – i.e. it establishes what has been called ‘his salvation-historical primacy.'”
John MacArthur (Protestant), Twelve Ordinary Men: “We know Simon Peter was the leader of the apostles—and not only from the fact that his name heads every list of the Twelve. We also have the explicit statement of Matthew 10:2: ‘Now the names of the twelve apostles are these: first, Simon, who is called Peter.’ The word translated ‘first’ in that verse is the Greek term protos. It doesn’t refer to the first in a list; it speaks of the chief, the leader of the group. Peter’s leadership is further evident in the way he normally acts as spokesman for the whole group. He is always in the foreground, taking the lead.”
