Was Peter not called to be the rock on which the Church was to be built? Sounds centralized to me.
Not at all. Christ said the least among you will be greatest in the Kingdom of Heaven. Christ himself exemplified his own teachings by washing the feet of his disciples, and giving up His life on the Cross.
This is reinforced in the book of Acts when Peter was making a decision on circumcision - Even though Peter was pro-circumcision, and argued with Paul extensively, he still listened to all, prayed, and received a vision explaining to him that it was okay not to be circumcised yet still be a Christian.
Peter never acted unilaterally or centralized, instead listened to all, and then asked God and Christ for help (since they are the true leaders of the Church), before giving his opinion. How Peter behaved on this subject is exactly how the Council of Nicaea was handled. The councilar nature of the Church was self-evident to all, which is why no universal Pope existed back then.
Additionally Peter was not just the Pope of Rome, but also the Pope of Jerusalem. None of the current Catholic history or theology surrounding Peter makes sense. Christ is King, and Christ left beyond a Holy Aristocracy to watch over his Church, even if one of those Aristocrats was to govern among them.
The assertion of the Universal Pope is why the Great Schism occurred, and the Protestant Reformation. Now we see the Pope pushing LGBT nonsense and if the next Pope is like this then the Catholic Church will experience nearly 100 years of extreme heresy (from 1965 - 2065).
How can any Catholic see all the troubles, and apostasy in their Church, and not conclude that the institution of the Papacy is the problem? How can Catholics not see the Orthodox Church with few of the problems of the Catholic Church, and not see the Papacy as the problem? It simply boggles my mind.
At some point, the cognitive dissonance for Catholics will be too great to bear - but I suppose there is still hope if the next Pope isn't a heretic. I think Benedict was supposed to be a decent Pope, but then he got forced out somehow and now the Catholic Church is suffering more than ever before.
My current Priest, who was a former Catholic, switched to Orthodoxy after Benedict "retired," because he was so disillusioned. Afterwards he met an Orthodox woman 25 years his junior, married her, and became a Priest in my diocese. Every Sunday I get to listen to great Catholic sermons, corrected with Orthodoxy, and watch his many children grow up in my Church.
I love the Catholic Church, in spite of it's many problems. I attended mass at the Notre Dame as a young man in 2008 and saw how wonderful it was, but there were less than 40 people in attendance for a Church that could house 20,000. I knew there were serious problems in Catholicism then.
I always pray for the reunification of Churches. But the commitment to the universal Papacy, when it is so clearly flawed and broken, continues to baffle me. No Catholic I speak with can ever give me good answers as to why it should continue.
"Ye shall know them by their fruits." And the fruits of the Papacy continue to be more and more fruitless as time goes on.
