Other Apostles...not addressing questions to Christ directly you say?
Balderdash.
Shall I now need go fetch examples for the contrary? How about doubting Thomas? Or those who questioned Him as who would be greater in the Kingdom of Heaven.... The list of those sort of interactions can go on, while at the same time, many of the responses of Christ to Peter --- can be seen in the texts as being addressed to the many (as the early church most certainly did most often interpret the NT) and most usually not given to Peter alone, as in being meant for Peter alone, but more sensibly also, to be commentary/instruction/teaching and answer being provided for all as to issues and aspects of God, and His truth.
Otherwise...should all now be required to listen to such as the Sermon on the Mount only from a [Roman] Catholic priest? We don't see there, or pretty much anywhere else Christ saying to Peter, "hey Petros 'ol pal, now that I have spoken -- would you interpret and explain what I just said directly to the multitudes?".
What can be seen later of course, is Peter standing up and explaining things to the Jews of his time, after the Assumption of the Risen Christ.
Many are called to that same mission...as was Paul.
How about instead of myself going and digging out scriptures where other Apostles do directly interact with the Christ, you go play fetch and bring to us here multiple instances of the other Apostles shrinking back, and in actuality pushing Peter forward while saying at the same time to Peter "you ask for us", instead of there being instances of Peter's own boldness of stepping forward (on his own 'get-go', as it were) rather than being "asked".
Even the one quote in Matthew 16, wherein "keys" were first mentioned by Christ as being given over to Peter, was itself spoken of again in Matthew chapter 18 with Christ there addressing all those whom were there assembled -- which leaves it reasonable enough for us to assume was much the reason why this later so-called 'primacy' of Peter, was understood in the early church to be a thing accessible to all through faith, with Peter (god bless him) frequently serving as example to the rest, and even to us still, to this very day.
>> Shall I now need go fetch examples for the contrary? How about doubting Thomas? <<
Go read the passage of doubting Thomas. He does NOT ask any questions to Jesus. He declares in Jesus’ absence that he would need to see proof of the Resurrection, and then Jesus appears to him and shows him the proof. No questions.
In every list of the apostles, Peter is called, “first.” But Andrew was the first apostle! True, Peter was first to see the risen Lord, but only because Peter stopped, and yielded to Peter! So, “Petrus, primus” refers not to Peter being first in chronology, but first in primacy!
>> Or those who questioned Him as who would be greater in the Kingdom of Heaven <<
There is no mention as to which asked him that. But he then repeated to the 12 PART of what he told Peter... and after that, Peter asks the questions (v. 21). And yes, many times he answered to the 12 together, but when he spoke of the keys of the kingdom, he specifically addressed Peter alone. When he directed, “shepherd my sheep,” he specifically addressed Peter alone.
At the transfiguration, who was there? Peter, James and John. At the Garden of Gethesemane, who was there? Peter James and John. To John, he left care of his mother. James would be glorified by martyrdom first. And Peter would lead.
>> would you interpret and explain what I just said directly to the multitudes? <<
That’s just stupid. Of course, he needs to instruct Peter first. But then when he is gone, who interprets the succession of Judas to the apostles (Acts 1) ? Peter. Who interprets Pentecost to the crowds (Acts 2)? Peter. Who interprets Joel and David? Peter. Who did Andrew yield to, arriving at the Tomb of the Resurrected Christ? Peter. Who speaks to the onlooker when the beggar was healed (Acts 3)? Peter. Who speaks to the Sanhedrin the apostles (Acts 4)? Peter. Who condemns Ananias and Sapphira? Peter. Whose shadow do people reach for to be healed (Acts 5)? Peter. Who advocates for the 12 in persecution? Peter. Who bests Simon the sorcerer (Acts 8)? Peter.
Whose vision, wthout seconding or interpretation by another apostle, leads to welcoming the gentiles and abandoning kosher laws, overturning Moses? Peter!
