There were 13 apostles, not just Peter.
.
I was sure the bible records Jesus chose the 12 disciples, 11 apostles received the commission to go out into the world and baptize every nation, people and tongue and only one apostle by the name of Peter received the commission by Jesus after His resurrection, to feed, tend the flock of Jesus, until Jesus returns.
In the book of Acts the eleven chose another to apostolic succeed Judas in order to re-establish the chosen 12 apostles.
St.Stephen a disciple of Jesus is martyred at the witness of Saul of Tarsus, James the Less is beheaded, Saul later is called by Jesus to preach to the Gentiles after Peter is given the vision to allow the Gentiles into the Church (Way). Paul lays hands on Timothy etc, etc…As the Apostolic Church developed the above offices to assist them to serve at the table of the Lord.
Originally Jesus chose the 12 to begin building His Church upon Peter when the Church is in her infancy.
In keeping with the OP, The Church experiences much growth to which the original apostles begin to lay hands on holy men to succeed them in their Episcopal office (overseer)= Apostolic office of Bishop, Deacons, and Priests. These all work in full communion with one another.
Yet it is only Peter whom Jesus singularly gives the keys to the kingdom of heaven to bind and loose on earth while Jesus binds and loose from heaven. The others are given the same keys to exercise at the local level in communion with Peter.
It is from this communion the Communion of the Popes and all bishops united as one, that the Church developed her doctrine to bind and loose heretics and heresies from infecting the teachings and revelations of Jesus Christ.
**Today, the Orthodox and Western Bishops maintain their apostolic powers to bind and loose at the local levels of the Church, yet for their powers to bind and loose on the whole earth, (or the whole Catholic Church) requires a communion with Peter’s chair to ratify and subject the binding and loosing to place effect on the whole of Christendom. This is how history records the dogma and doctrines of the Church to develop over the centuries in a nutshell. **
An apostolic successor by himself cannot develop Church doctrine that binds and looses on the whole earth (Church). To bind and loose on the whole earth requires the chair of Peter who alone possesses the keys to bind and loose on earth. That is not a decision of man, that is a direct commission from God Himself recorded in the Gospels.
The Church from her infancy has more than 13 apostles world wide to today.
Peace be with you
