All of those people were meeting in someones home. Not one instance of a dedicated building. None of the verses you sited show and organized structure such as you seem to be promoting.
>> Matthew 16:18 - And 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.<<
In Matthew 16 Jesus is talking to all of the Apostles. They were all asked the question of who they thought He was. Though Peter was the one who answered for the group Jesus was talking to them all. When Peter said that they believed He was Christ the Son of the Living God Jesus replied and said that it was not flesh and blood that had revealed that to Peter but that it was my Father which is in heaven. He then says to Peter and thou art Peter, acknowledging that He knew who Peter was just as Peter knew who Jesus was. Then Jesus, referring back to my Father which is in heaven, says, upon this rock I will build my church.
In other places in scripture Jesus is referred to as the corner stone, but the rock that the church is build on is the Father.
If you want reference to God as the Rock here are some verses.
Deut. 32:4 He 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.
2 Sam. 22:2 And he said, The LORD is my rock, and my fortress, and my deliverer; 3 The God of my rock; in him will I trust: he is my shield, and the horn of my salvation, my high tower, and my refuge, my saviour; thou savest me from violence.
Psalm 18:31, "And who is a rock, except our God."
Isaiah 44:8, "Is there any God besides Me, or is there any other Rock? I know of none."
Well then you must not need other people to help you in your walk. Nor does anyone need your help.
Or your heart is hard.
hmmmmm
"Understanding this first, that no prophecy of scripture is made by private interpretation. For prophecy came not by the will of man at any time: but the holy men of God spoke, inspired by the Holy Ghost." 2 Peter 1:20-21
