'k, bible verses included for you to ponder; actually, this was pretty fun; maybe in the future i'll tackle other contraversial issues that God has seemingly showed me in the scriptures, like why free will's not supported by the bible, or why israel will NOT be restored in the endtimes, more in-depth why the roman catholic church's the antichrist, but it took me a while to write all this, so i'll just sit back now:

jesus calling simon as 'peter,' then saying upon this rock will i build my church...
Matt:16:17-19
17And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.
18And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
19And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.

roman catholics take this verse and assume that peter built the 1st church.

and from the wording of the bible(check it; it's the same for all versions), it would SEEM to suggest that the church is built upon peter(although, i might add, kjv has no footnotes stating that peter means rock, which helps ease off the confusion).
look at the NIV footnotes, then try the KJV version

but wait... there's numerous other references to a so-called 'rock' in the other parts of the bible... do they apparently seem to refer to peter as this rock, or jesus as the rock?
Deuteronomy 32:4
4He is the Rock, his work is perfect: for all his ways are judgment: a God of truth and without iniquity, just and right is he.
1st Corinthians 10:4
4And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.

the 'rock being cut out not by human hands' in daniel, is this peter, or jesus?
Daniel 2:34-35,44,4-5
34Thou sawest till that a stone was cut out without hands, which smote the image upon his feet that were of iron and clay, and brake them to pieces.
35Then was the iron, the clay, the brass, the silver, and the gold, broken to pieces together, and became like the chaff of the summer threshingfloors; and the wind carried them away, that no place was found for them: and the stone that smote the image became a great mountain, and filled the whole earth.
...
44And in the days of these kings shall the God of heaven set up a kingdom, which shall never be destroyed: and the kingdom shall not be left to other people, but it shall break in pieces and consume all these kingdoms, and it shall stand for ever.
45Forasmuch as thou sawest that the stone was cut out of the mountain without hands, and that it brake in pieces the iron, the brass, the clay, the silver, and the gold; the great God hath made known to the king what shall come to pass hereafter: and the dream is certain, and the interpretation thereof sure.

the foundation that the wise man builds in jesus' parable ON THE ROCK, think this is peter, or jesus?
Matt 7:24-25
24Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:
25And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.

the capstone that the builders have rejected; is this peter, or jesus?
(this is also the stone that was cut out not by human hands that is described in daniel)
Isaiah 8:13-16
13Sanctify the LORD of hosts himself; and let him be your fear, and let him be your dread.
14And he shall be for a sanctuary; but for a stone of stumbling and for a rock of offence to both the houses of Israel, for a gin and for a snare to the inhabitants of Jerusalem.
15And many among them shall stumble, and fall, and be broken, and be snared, and be taken.
16Bind up the testimony, seal the law among my disciples.
Psalm 118:22
22The stone which the builders refused is become the head stone of the corner.
Matt 21:42-43
42Jesus saith unto them, Did ye never read in the scriptures, The stone which the builders rejected, the same is become the head of the corner: this is the Lord's doing, and it is marvellous in our eyes?
43Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof.
44And whosoever shall fall on this stone shall be broken: but on whomsoever it shall fall, it will grind him to powder.

the statement that 'their rock is not our rock,' think this refers to peter, or to jesus?
(this passage, based upon the ebook that i was reading, interprets this this verse to mean that Protestants' rock is Jesus Christ, and the Catholics' rock is Peter, since he "supposedly" founded the church, since he is the head and replaces Jesus, he is THEIR rock)
Deuteronomy 32:31
31For their rock is not as our Rock, even our enemies themselves being judges.

if peter is the head of our church, then why doesn't the epistles state that peter's the head of the body of christ, and we are the body(we know that the body of christ is the church)?
Ephesians 5:23-24
23For the husband is the head of the wife, even as Christ is the head of the church: and he is the saviour of the body.
24Therefore as the church is subject unto Christ, so let the wives be to their own husbands in every thing.
Colossians 1:18
18And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.

what does paul say about being divided in the body of Christ?
1 Corinth 1:12-15
12Now this I say, that every one of you saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ.
13Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?
14I thank God that I baptized none of you, but Crispus and Gaius;
15Lest any should say that I had baptized in mine own name.

does peter even seem to like the idea of being revered as a saint? the italian man who invited him to his house bowed down to him, but peter made him stand right back up, telling him, he was only a man himself.
Acts 10:25-26
25And as Peter was coming in, Cornelius met him, and fell down at his feet, and worshipped him.
26But Peter took him up, saying, Stand up; I myself also am a man.

furthermore, there is no reason to suggest peter was even an apostle TO the gentiles; that role was fulfilled by paul, and the main powerhouse for the jews was peter. when paul greets all the christians in rome in his letter "romans", nowhere is it seen that he greets peter. NOWHERE.
Romans 11:13
13For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office:
Galatians 2:7-9
7But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;
8(For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles:)
9And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.
read this, and tell me if paul ever greets peter in his letter to the romans
