Some of your answers grieve me. we do not need a human being to legislate on matters of salvation. Salvation is the Father's to give and the Bible says whom the Father has given Christ in salvation, Christ will lose nothing.
Friend, Rome has you brainwashed. I looked at your link before. It MAY give evidence to Peter's having been in Rome, but no contemporary sources speak of it.
The saddest part of your answer is concerning the Holy Spirit. He most certainly DID give the Holy Spirit to every believer.
John 7:38-40
38He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water.
39(But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.
Acts 2:4
And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
Ephesians 1:13
In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise
Ephesians 4:30
And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
1 Thessalonians 4:8
He therefore that despiseth, despiseth not man, but God, who hath also given unto us his holy Spirit.
John 14:16
And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
John 14:26
But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
John 15:26
But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me:
John 16:7
Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.
What do you think a possession of the keys to the Kingdom of Heaven signify? I just read what is written.
He most certainly DID give the Holy Spirit to every believer
This is how that is described:
When he had said this, he breathed on [the disciples gathered in the upper room]; and he said to them: Receive ye the Holy Ghost (John 20:22)I don't see anyone but a select group in there. Now, it is true that the Church gives the gift of the Holy Spirit to those the Church sacramentally confirms. I don't think I argued otherwise.
