So we agree he was teaching error ...how infallible!
It was Peter who was first divinely inspired to liberate Gentiles from the OT laws at the Gentile household of Cornelius.
Indeed he did..That was a gift from Christ to his friend..THAT is what Christ meant by the keys to the Kingdom.....Keys are only good for one thing..to open doors, once opened they have no more value ..
Peter was the first to proclaim Christ as Savior... To open the door to the gospel to both jews and gentiles
Mat 16:16 And Simon Peter answered and said, Thou art the Christ, the Son of the living God. :17 And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed [it] unto thee, but my Father which is in heaven.
Peter was given the privilege of opening that very gospel to Jews and Gentiles.. BUT His primary ministry..ACCORDING THE SCRIPTURE was to the Jews.. and Paul to the gentiles..
Gal 2:7 But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as [the gospel] of the circumcision [was] unto Peter;

Peter writes to the scattered and exiled jews
1Pe 1:1 Peter, an apostle of Jesus Christ, To those who reside as aliens, scattered throughout Pontus, Galatia, Cappadocia, Asia, and Bithynia, who are chosen
1Cr 3:19
Peter was taking meals erroneously but not teaching error. If he had been teaching the error, it would not have become magically infallible since it would have conflicted with the teaching about Christians not having to keep kosher.

Christ's kingdom is likened to a city, the New Jerusalem. Cities at that time, including Jerusalem, had gates that were unlocked with keys. The king usually held the keys. In preparation for a journey, the the king would appoint a steward or vicar to hold the keys until his return. The key-keeper was in charge of defending the city and enforcing or clarifying the laws until the king returned. That is the role of Peter and his successors.
