Hmmm, then you go on to say:
The Body of Christ includes all those adopted into Gods family, all those who follow Christ
I have no disagreement with this, as far as it goes.
Here's the problem, Theo: on whom does Christ bestow earthly responsibility and leadership for His Body?
God has provided “overseers and deacons” (or “bishops and deacons,” depending on your translation) to bear earthly responsibility and leadership for His Body.
Scripture describes these men, and their roles/responsibilities, in 1 Tim. 3:1-13, Acts 20:28, Hebrews 13:17, Eph. 4:11-12, 2 Tim. 2:2, Acts 14:23, and elsewhere.
