Peter was first just because he was the most flamboyant??? LOL, that makes a lot of sense.
This is the kind of nonsense people resort to in order to deny the truth of Catholic doctrine.
Hat tip to daniel
"Peter" mentioned by that name 162 times in all of the New Testament, sometimes together as "Simon Peter," and separately as "Cephas" 6 times, and separately as Simon 17 times at most, for a total of 185. In addition, a cursory count finds other apostles are mentioned by name about 80 times.
