You do understand what is meant by a regenerate church membership, right (see chapter 26 of our confession)? Baptists do not consider unconverted persons to be members of the body of Christ. Baptists do not deny that false professors are in the church (Jude), but they are not members of the invisible church (1689 LBC 26.1).
Can a non member baptize people in a baptist church?
Can a non member ordain men for ministry?
