The primacy of Peter, also known as Petrine primacy (from Latin: Petrus, "Peter"), is the position of preeminence that is attributed to Saint Peter among the Twelve Apostles.
It is to be distinguished from the primacy of the Bishop of Rome, also known as papal primacy or Roman primacy, whose link with the primacy of Peter is disputed.
The Evangelical Dictionary of Theology illustrates the leading role that Peter played among the Apostles, speaking up on matters that concern them all, being called by Jesus by a name linking him with the rock on which Jesus would build his church, being charged with pasturing the flock of Christ, and taking the leading role in the initial church described in the Acts of the Apostles.
There is general agreement among scholars on the preeminence that the historical Peter held among the disciples of Jesus, making him "the most prominent and influential member of the Twelve during Jesus' ministry and in the early Church".
In one interpretation the prominence that the New Testament and other early Christian writings attribute to Peter is due to their seeing him as a unifying factor in contrast to other figures identified with disputed interpretations of Christianity.
Controversy has surrounded one particular text that is linked with the Aramaic nickname name כפא (Cepha), meaning "rock," that Jesus gave the man previously known as Simon. The Greeks translated it as Πέτρος (Petros), a new form, appropriately masculine, of the standard feminine word πέτρα (petra), also meaning "rock;" and the Latins translated it as Petrus.
Since the Protestant Reformation, many non-Catholics, in disagreement with the historic Catholic Church view, have disputed whether the feminine πέτρα refers to Peter, claiming it instead refers to either Peter's confession of faith or Jesus himself. Yet, both of these traditional explanations of this passage have been termed incorrect by some recent Catholic Bible scholars.
While the reasons for disagreement on the nature of the primacy are complex—hinging on matters of doctrine, history, and politics, the debate is often reduced to a discussion of the meaning and translation of the "on this rock" passage:
And I say also unto thee, that thou art Peter [Greek, Petros, rock, masculine], and upon this rock [Greek, petra, rock, feminine] I will build my church; and the gates of hell shall not prevail against it.
