The Ignatius Insight blog had an interesting link (the link has died, a search for "ravenna" at HPR can bring it back, or check the Google cache) on the "historical fact" of the Roman Primacy.
Of course, it is a fact, in terms of "something that actually happened".
An interesting quote:
"our Lord Jesus Christ gave the ministerial leadership of his Church to Peter and intended this office (like the Church itself) to continue permanently"Peter had the office and gift of apostle. This is effectively a form of continuationism (the opposite of cessationism).
The Internet Monk recently commented on "The Coming Evangelical Collapse". In part 2, he sees a strong movement toward Charismatic-Pentecostal theology. This theology is also strongly continualist (I recently attended a church headed by an "Apostle").
