‘Not only will our Lord use it, but it is transliterated into Greek in the Pauline letters as
Kephas (1 Cor 1:12; 3:22; 9:5; 15:4; Gal 1:18; 2:9,11,14. John 1:42 translates it as
Petros. Considering the text alone, and even many Protestant scholars today admit as much, the “rock” upon which the Church will be built is Peter.

‘
Petros is only a translation of the original Aramaic name of Peter, which is *Kephas *(
Cephas in its English form). It should be understood that although the New Testament was almost entirely written in Greek, Jesus and the Apostles spoke Aramaic, the Hebrew dialect. In Aramaic, the word for rock is
kephas, which unlike its translation in Greek, is free from any gender influence. Thus, the Lord’s statement in Mt 16:17 is more accurately rendered as: “You are
Kephas and upon this
kephas I will build my Church.” The Bible, quoting the Lord Jesus, states this clearly in John 1:42. The verse reads: "Jesus looked at him [Peter] and said, ‘You are Simon the son of John; you will be called
Cephas (which is translated as Peter).’’ "St. Paul also called Peter by his Aramaic name in 1Corinthians 1:12 and Galatians 1:18.

As Jimmy Akin testifies:
“the Greek Septuagint translation is
petra”

‘Peter the rock cannot be separated from the faith of his confession, but the rock has direct reference to Peter himself, not just the faith of his confession, as Evangelical and Protestant scholars now widely and correctly affirm.
‘Among the chorus of voices in this regard, as I will document eventually, are F. F. Bruce, D. A. Carson, Walter Elwell, R. T. France, Herman Ridderbos and Craig Blomberg. Thus Chrys C. Caragounis writes: “After centuries of disagreement it would appear that Protestant and Catholic are at last united in referring the rock upon which the Church according to Mt 16:18 is to be built, to the Apostle Peter” (Caragounis 1).’

That reality added to the specific establishment of St Peter as His Chief Vicar in His Church confirms the unassailable facts.
**All four promises to Peter alone: **
“You are Peter and on this rock I will build My Church.” (Mt 16:18)
“The gates of hell will not prevail against it.”(Mt 16:18)
“I will give you the keys of the Kingdom of heaven." ( Mt 16:19)
“Whatever you bind on earth will be bound in heaven.” (Mt 16:19) [Later, also to the Twelve].
**Sole authority: **
“Strengthen your brethren.” (Lk 22:32)
“Feed My sheep.”(Jn 21:17).
So the other Apostles were not given the supreme authority given to Christ’s Supreme Vicar, and no other church has been founded by Christ Himself, with His mandate and protection from teaching error in dogma and doctrine to the whole Church on faith or morals.
