SFPW, it is not Unity.. it is Conformity. There's a difference. Look up Groupthink in Wikipedia. George Orwell uses it quite nicely in his novel 1984.
And when did the 1stC christians have to put in a field service report? They never had to 'report back' to anyone, they were all over the place yet look how they accomplished it!
Today there are over 1,000,000 christians in China without any kind of 'organisation'. They meet in 'house churches' much the same as 1stC christians did.
Also, you have taken 1 Cor 14:33 out of context. There is nothing wrong with being organised to accomplish something. Where it becomes wrong is when IT becomes an ORGANISATION that controls people.
