The pope is your prophet king and priest ... another christ ...the head Alter Christus...
According to Church teachings, Christ's is The Priest Prophet and King, and all baptized Catholics (including the pope and you too, by the way) are called to imitate Him in all three of those roles.
As for your continual harping on "Alter Christus" as a heresy or whatever you think it is, I suggest you reread Luke 22: 19-20.
