Well, there wasn't much of a list in 67 AD when he and St. Peter, our first pope were both executed. But, as to the various roles that people serve in the body of the Church;
1 Corinthians 28. "And in the church God has appointed first of all apostles, second prophets, third teachers, then workers of miracles, also those having gifts of healing, those able to help others, those with gifts of administration, and those speaking in different kinds of tongues."
Various popes have served in all those capacities throughout history, though I imagine the gifts of administration would be essential to their official capacity.
Speaking of the Body of the Church, we had some applicable readings on that today at mass.
Our good Freeper, Salvation is kind enough to post daily mass readings here on Free Republic. Not only is it a blessing to Catholics and other interested Christians, but it has served to help dismiss the false myth that Catholics don't read the Holy Bible.

Is this anything like Jumbo Shrimp or
Military Intelligence?
Sure you merely mean 'myth'; for a 'false myth' would equal truth!
