My vote John XIV is because St. John the Baptist is the greatest prophet closing the line of the prophets of the Old Testament, and in today’s faithful world we handle a lot of attempted prophecising. Jesus never said a prophet will succeed him. One way or the other God will remind the Christian world that, after the prophets now it is time for the apostolic work.
John in Hebrew Yochanan means God is full of grace or God is merciful.
I truly believe the next pope will be a Yochanan.
