You guys do realize, don't you, that Jesus established the genesis of an organized, hierarchical Church, modelled on the Family of God, Israel?
Jesus chose apostles, made Peter the leader, and gave them authorities that all the other disciples did not have. Later, in Acts, the hierarchy develops further. The apostles appoint Deacons (greek - diakonos ), Priests (greek - presbyteros ), and Bishops (greek - episkopos), and each have different duties. It is the same today in the Catholic Church.
This is a perfection of Israel's pyramid, with Abraham at top, then the fathers of the twelve tribes, then the lesser clans. Israel, the People of God, were the Family of God, and they were truly family by blood. When Jesus expanded the covenant to all peoples, the Family of God became bound by spirit, not just blood, but the structure was the same. That is why we call priests "father, call each other brothers and sisters, and so forth.
What many of you call "organization" is actually the family structure of the Church, the Family of God.
And on a lesser, administrative level, organization is a neccessity. Even if you have a single, one-building unaffiliated church, you need a secratary, someone to pay the bills, someone to habdle paperwork. Of course, Christ's Church was intended top span the globe, and with a global organization comes..... ......well, comes global organization.
The idea of un-organized religion is a pipe dream and is un-Biblical.
As for abuses: Ever heard of Judas? There were abuses from day one. When humans are present, so is sin. You can have a one-man church and you will STILL have sin, because we are all sinners.
