Pope Francis I
I'm not a Catholic, but the Roman Church has always fascinated me because of its rich history, pageantry, complex hagiography and its patronage of the arts. Besides, in many ways he is the face of Christianity - I may not agree with every doctrine of the Church but I think my interests and beliefs align more with the Catholic Church than, say, Billy Graham. In fact, I'd probably convert to Catholicism the devotion to the saints didn't seem so...well, sacrilegious.
Anyway, given the many problems that have plagued the Catholic Church in recent years, I'm very curious to see just what sort of Pope this Francis shall be.
