Contrary to the fancies imagined by Mystophilus in post #12, the Son of God expressly and very clearly built His Church in His own words:
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 to the Twelve]
**Sole authority: **
“Strengthen your brethren.” (Lk 22:32)
“Feed My sheep.”(Jn 21:17).
Already, Peter had exercised his supreme authority in the upper room before Pentecost to have Judas’ place filled. At the first Apostolic Council of Jerusalem Paul made sure that his ministry to the gentiles was recognised by, Peter (Gal 1:I8).
Christ gave no one else the authority that He gave to St Peter alone. Having built His Church on St Peter He promised the Holy Spirit’s guidance to “all truth”:
“I will not leave you orphans; I will come to you." (John 14:15-18) “The Advocate, the Holy Spirit that the Father will send in My name, He will teach you everything and remind you of all that I told you.” (John 14:26) “But when He comes, the Spirit of truth, He will guide you to all truth. He will not speak on His own, but He will speak what He hears, and will declare to you the things that are coming. He will glorify Me, because He will take from what is mine and declare it to you. Everything that the Father has is mine; for this reason I told you that He will take from what is mine and declare it to you.” (John 16:13-15).
The words of Christ need to be heeded by all who would be Christians.
