Let me rephrase what I said. I am not persuaded that the instruction to confine their ministry to the lost sheep of the house of Israel remained in force after the resurrection, whoever the lost sheep of the House of Israel might be.
May the Lord bless whatever medical monkey business you have to endure.
Except this theory collapses on one key issue. The Church was the SOLE CUSTODIAN of all Scripture and writings of the early Church fathers for FIFTEEN CENTURIES. If they had engaged in this conspiracy, they would simply have destroyed all of the evidence.
NONE of the original Protestant Reformers questioned the FACT that Peter was the first Pope or that he was in Rome, this Simon Magus theory is a VERY RECENT invention by anti-Catholics. Here are two of Luther's "95 Theses" which clearly indicate that he never questioned the fact that Peter was the first pope (obviously, Luther did question papal authority):
77. When it is said that not even St. Peter, if he were now pope, could grant a greater grace, it is blasphemy against St. Peter and the pope.
78. We assert the contrary, and say that he, and any pope whatever, possesses greater graces, viz., the gospel, spiritual powers, gifts of healing, etc., as is declared in I Corinthians 12:28.
While it is clear that both of these statements question mock the papacy, they also AFFIRM THE FACT that Peter was the first pope.
