There was an informal link of scriptural baptism. And, there was apparently an informal link by preachers involved who had been in the church in Jerusalem before being driven o ut of Jerusalem by persecution. Ninth and finally , I have never advocated that a group of unbaptized believers could come together and baptize one another and form a church. Also, I have never advocated the idea that a group of Scripturally baptized believers who have been excluded on charges that are set forth in Scripture as grounds for exclusion, and who have been excluded in a Scriptural manner and attitude, could gather and constitute themselves into a church. Those who charge that I have advocated such are guilty of railing, an excludable offense.
Churches do make mistakes and are sometimes unwilling to admit it.
I am thinking of at least five or six situations in which churches acted in very unscriptural manners in the exclusion of members who were later constituted into a church. Let me relate two of those. In the state of Louisiana a little over 35 years ago a Pastor of a Southern Baptist Church came to believe the doctrines of grace. He also held to what Old Landmark Baptists held. A good group of members came to see the doctrines of grace with him.
