So which is it Rock or Satan?
Not ONE apostle or early father ever even hinted that Jesus made Peter the head of the church.. Peter never claimed it for himself. Such silence is deafening. The first person to propose this was a Bishop of Rome in the 4th century. Over 300 years after Christ
I don't know the date. It is a linguistic question.
which is it Rock or Satan?
In Matthew 16:23 Christ is addressing Satan, not Peter. When Peter suggested that Christ forbids His Passion from happening, unknowingly he repeated the temptation of Christ to become a temporal ruler by Satan, and Christ rebuked Satan once more. It is clear that He continued to love Peter as He charged him with the stewardship of the sheep later. Peter's proneness to error prior to Christ's resurrection, combined with his unflinching recognition of Christ the Son of God is the reason Peter was chosen to be the foundation of the Church, which is also infallibly lead by fallible men.
Such silence is deafening
What silence? I just gave you scriptural and patristic references from early 1 century in my 175.
