Who gets to define “Christian”?
Jesus Christ -> St. Peter -> Linus [ ... ] -> Bl. John XXIII -> Paul VI -> John Paul -> John Paul II -> Benedict XVI
That’s who.
Jesus Christ
Just in case you forgot there were eleven other apostles.
And I listed him who would be first last, as is appropriate.
Matthew 20:25-28
Jesus called them together and said, "You know that the rulers of the Gentiles lord it over them, and their high officials exercise authority over them. Not so with you. Instead, whoever wants to become great among you must be your servant, and whoever wants to be first must be your slave— just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many."
