Related to my last post is the question of authority. Roman Catholics attack Protestantism and Orthodoxy because they do not have a central authority figure - namely, the pope. They are especially critical of Anglicanism because it is so close to Romanism in terms of its liturgy and theology. They want us all to convert, and "go the whole way", if you will. Of course, there is no need to convert. Anglicans are Catholics - the only diffference being we have not checked our brains at the door.
Romanists assume that their infallible pope, who has greater authority than an ecumenical council, is somehow a safeguard against heresy. They fail to realize, however, that even popes can err, and that sometimes greatly. Just look at the history of the church. The Roman Pontiffs have committed great sins in the past. Why? Because they are human beings, and have a sinful nature like the rest of us. The errors of the past make the recent sex abuse scandals look like nothing, in fact. On the eve of the Reformation the Roman Church and curia were hopelessly corrupt. They cleaned up their act, to be sure, and JPII has been a wonderful witness of the gospel. But who is supposed to have that much power? That much power in the hands of some who would abuse could destroy the church more than anything else before it. And why papists don't realize that... and why it doesn't scare their pants off... is utterly beyond me. Authority in the Church is vested in Scripture and Tradition, and it is up to the Bishops of the Church to interpret them in a way that is normative for the life of the Church. And this is done in a collegial manner.
It is worth noting that even though Rome has these strange and heretical doctrines such as papal infallibility and supreme authority that they decide on matters of faith in the same way as other churches, and the pope in most cases simply "rubber stamps" things. The pope, in other words, has mountains of advisors and theologians who look at Scripture and Tradition, in light of human reason and natural law, when deciding about matters of the faith that may arise later on (such as bioethical issues). The pope rubber stamps this. He doesn't just pull new doctrines out of thin air, in other words.
Well, that is what other churches do too. That is what the Orthodox do, and the we do, and other Protestants do. At the end of the day, we have to the honesty to confess that it is a collegial process, whereas the papists give the pope all of the credit. But the crucial difference is the authority of the pope. The fact that, at the end of the day, the pope can come down and say and do whatever he wants is exceedingly frightening and unchristian, and I want no part in it. Christ ordained 12 apostles, not 1 and 11 assistants.
