No human is infallible, popes especially so. Given the long history of really awful stuff propagated by the catholic church as a useful tool of various kings and other petty tyrants, I cannot see anything that looks like it is Chris-centered for most of the instanciation of the papacy. 

Peter was not infallible, and there is nothing that I'm aware of that shows that Jesus intended for there to be a single, centralized person to be in charge of all of Christendom other than Himself. As I like to say: "No king but Christ." I have no need of anyone else to lead the church (meaning all believers in Christ, of all flavors, though, there are plenty of heretical beliefs floating around, and I'm not sure it's exactly correct to just say "believers" anymore given that I know more about our enemy these days). 

I'm usually up for discussions, though, I'm definitely not wanting to be antagonistic as that is fruitless. 😁
