Here is the sin of the traditional church...
3 John 1:9-10 (King James Version)
9I wrote unto the church: but Diotrephes, who loveth to have the preeminence among them, receiveth us not.
10Wherefore, if I come, I will remember his deeds which he doeth, prating against us with malicious words: and not content therewith, neither doth he himself receive the brethren, and forbiddeth them that would, and casteth them out of the church.
We have pastors who want preeminence among the flock. Pastors often do not receive other churches and/or ministers in fellowship. They also often don't receive the calling and ministries of others in their congregation. Sadly, the spirit of Diotrephes us alive and well.
