A good exegesis of the Rock passage (in response to Robert Sungenis' book):

And about those "33,000 denominations":

Also, I'm interested in how you would respond to Galatians 2:11-12:

Quote
11 But when Cephas came to Antioch, I opposed him to his face, because he stood condemned.
12 For prior to the coming of certain men from James, he used to eat with the Gentiles; but when they came, he began to withdraw and hold himself aloof, fearing the party of the circumcision.
13 The rest of the Jews joined him in hypocrisy, with the result that even Barnabas was carried away by their hypocrisy.
14 But when I saw that they were not straightforward about the truth of the gospel, I said to Cephas in the presence of all, "If you, being a Jew, live like the Gentiles and not like the Jews, how is it that you compel the Gentiles to live like Jews?
15 "We are Jews by nature and not sinners from among the Gentiles;
16 nevertheless knowing that a man is not justified by the works of the Law but through faith in Christ Jesus, even we have believed in Christ Jesus, so that we may be justified by faith in Christ and not by the works of the Law; since by the works of the Law no flesh will be justified.
17 "But if, while seeking to be justified in Christ, we ourselves have also been found sinners, is Christ then a minister of sin? May it never be!
18 "For if I rebuild what I have once destroyed, I prove myself to be a transgressor.
19 "For through the Law I died to the Law, so that I might live to God.
20 "I have been crucified with Christ; and it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself up for me.
21 "I do not nullify the grace of God, for if righteousness comes through the Law, then Christ died needlessly."

Surely you couldn't say that this was a private, personal teaching of Peter, could you?

True godliness is a sincere feeling which loves God as Father as much as it fears and reverences Him as Lord, embraces His righteousness, and dreads offending Him worse than death~ Calvin
