Churches are all creations of men.
There is not one word in the Bible about any corporation being ordained to make Yehova’s rules. The word used in the Bible is Congregation, not church. His congregation is invisible, and will be sorted out from the tares at the day of trumpets; until then the tares will run the churches.

The Bible, of which you speak, was brought to you through the efforts of the Catholic CHURCH....while the word church may not be used in the Bible, the group of Christians which followed Christ and continued to grow and prosper after His death decided to call themselves the Catholic church....very descriptive and meaningful terminology.
