I get that you left that church because of the obvious moral compromise of the pastor. You are mistaken, however, in believing the sexual sin of a suboordinate minister would have been prevented by a better pastor. Sexual sin exists in the strictist of fellowships. It is, and probably will always be, the thorn in the side of ministry. The decision for any individual to sin comes from the deficits in their own walk with God, not their pastor's.
