Papacy & the Church
Peter's Role in Scripture
Throughout the New Testament, Peter consistently appears first among the apostles, speaking and acting as their spokesman and leader.
Catholic teaching
Peter's primacy is not a later invention read back into the text but is woven throughout the Gospels and Acts, where he alone is renamed by Christ, listed first in every apostolic roster, and takes the lead at Pentecost, the first council, and in matters of doctrine and discipline. This textual pattern corroborates Christ's explicit commissioning of Peter in Matthew 16 and John 21.
Biblical foundation
Every list of the apostles in the Gospels names Peter first, even though the apostles were not called in that order chronologically. Peter preaches the first public sermon at Pentecost, and he presides in resolving the first great doctrinal dispute of the Church at the Council of Jerusalem.
Scripture references
Historical evidence
Early Christian writers such as Eusebius of Caesarea, drawing on earlier sources, consistently identify Peter as having founded and led the church at Rome before his martyrdom there under Nero, a tradition attested from the earliest surviving Roman episcopal lists.
The Church Fathers
“He builds his Church upon that one man, and although after his resurrection he bestowed equal power on all the apostles... yet, in order that he might set forth unity, he arranged by his own authority the origin of that unity as beginning from one.”
