Uh, no, he didn't. Haven't you actually read Kefa's own interpretation of his vision? "You know how unlawful it is for a Jewish man to keep company with or go to one of another nation. But God has shown me that I should not call any man common or unclean" (Acts 10:28).
Kefa himself said that his vision had nothing to do with food; that was just the symbol God used. Further, Kefa quotes the following in his first epistle: "Be holy, because I am holy" (1 Pt. 1:16). Now go look up where that phrase occurs:
Lev. 11:44-45 - right in the middle of the kosher commandments.Hmm . . . he seems to have liked the kosher commandments, since two out of the three places he could have been referring to give them (two out of two if we consider Lev. 19 & 20 to be of a piece, as I do).Lev. 19:2 - heading up a section which reiterated commandments ranging from keeping the Sabbath, to treating your neighbor correctly, to not eating anything with blood (v. 26), a commandment linked back to the kosher laws.
Lev. 20:7 - heading up a second section reiterating commandments of both sexual purity and the kosher laws.
So, no, Kefa was most certainly not getting, "Go have a pork and lobster sandwich" out of his vision.
The moving of the Sabbath from Saturday to Sunday has nothing to do with St. Paul either.
It had nothing to do with any Apostle, nor the Lord, since no such change of the commandment is so much as mentioned in the NT--and in fact, Heb. 4:1-11 makes a point of saying that we should still rest from our works on the seventh day as God did from His.
The Council approved pork and lobster sandwiches right after St. Peter spoke, so I would think they understood him better than you, not being there, did.
I agree, by the way, that the ceremonial purity and dietetic laws of the Old Testament played an important part in the economy of Salvation. They are prefigurement of Our Lady's purity.
When was Sunday first celebrated as Resurrection Day?
