Re the ECFs, St. John Chrysostom in his treatise On the Priesthood, Book 1, ch. 2:
’And I say unto thee, Thou are Peter, and upon this rock I will build my Church’: that is,
on the faith of his confession .” (NPNF Vol. 10, p. 333)
“(Jesus) speaks from this time lowly things, on His way to His passion, that He may show His humanity. For
He that has built His church upon Peter’s confession , and has so fortified it, that ten thousand dangers and deaths are not to prevail over it…” (NPNF Vol. 10, p. 494)
“For the son of thunder, the beloved of Christ, the pillar of the Churches throughout the world,
who holds the keys of heaven , who drank the cup of Christ, and was baptized with His baptism, who lay upon his Master’s bosom, with much confidence…” (NPNF Vol. XIV, p. 1)
This (James) was bishop, as they say, and therefore he speaks last…There was no arrogance in the Church. After Peter Paul speaks, and none silences him: James waits patiently; not starts up (for the next word). Great the orderliness (of the proceedings). No word speaks John here, no word the other Apostles, but held their peace,
for James was invested with the chief rule , and think it no hardship. So clean was their soul from love of glory. And after that they had held their peace, James answered. Peter indeed spoke more strongly, but James here more mildly; for thus it behooves one in high authority, to leave what is unpleasant for others to say, while he himself appears in the milder part…” (NPNF Vol. XI, p. 205, 207)
St. John Chrysostom On the Papacy
it may seem like a mixed bag. Anyways , for sure by 4-5 century we see strong development of papacy justification, as i posted earlier.
