Well,
As far as proselytizing goes, it's true that the word of G-d through Y'shua had been said we are to spread His words throughout the world; but I have not yet recalled a time when He commanded the disciples/apostles/saints to create a specific grouping of people and have them abide under the rule of elders, etc. He did give His disciples authority over demons, to do healings, and even made mention of princes of the Gentiles to execute authority(Matthew 20:25-28)... authority under a specified creed however:
26 But it shall not be so among you: but whosoever will be great among you, let him be your minister;
27 And whosoever will be chief among you, let him be your servant:
28 Even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many."
Didn't he try to get people to avoid the tradition of the elders?
Even when Y'shua had made mention of the "church" being built... Matthew 16: 18-19 "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.
19 And 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.", the reference is put into context of Heaven against hell... knowing that he must die and be resurrected, so that the world might be saved through Him.
The prophet Isaiah had wrote in chapter 66, verse 1-2 "1 Thus saith the LORD, The heaven is my throne, and the earth is my footstool: where is the house that ye build unto me? and where is the place of my rest?
2 For all those things hath mine hand made, and all those things have been, saith the LORD: but to this man will I look, even to him that is poor and of a contrite spirit, and trembleth at my word.", the almost exact quoting was written in Acts 7: 47-51
"47 But Solomon built him an house.
48 Howbeit the most High dwelleth not in temples made with hands; as saith the prophet,
49 Heaven is my throne, and earth is my footstool: what house will ye build me? saith the Lord: or what is the place of my rest?
50 Hath not my hand made all these things?
51 Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost: as your fathers did , so do ye."
Resisting the Holy Ghost!? What does the Holy Ghost have to do with it all... John 14:26 & Likewise Hebrews 10:15-18. All of which, under the circumstances, require our obedience to the same commandments Y'shua had given us to hang all the law and prophets on...
Matthew 22:37-40
John 14:26 "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."
Hebrews 10:15-18 "15 Whereof the Holy Ghost also is a witness to us: for after that he had said before,
16 This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;
17 And their sins and iniquities will I remember no more.
18 Now where remission of these is, there is no more offering for sin."
*Note: Please, if you really wanted to understand the completeness of that covenant... read through the rest of that Chapter in Hebrews.
