FB#14 says the source of  our unity is the oneness of the triune God. Jesus Christ did not grasp equality with God, he took on himself the form of a servant. The priesthood of all believers, the notion that we are all equal in Christ, is not derived from our nonexistent  'sameness' or equal status.  Our unity and equality is derived from Christ's status as God and King and Sacrifice. The chosen are equally chosen - not the chosen are equal. We are not a kingdom of high priests.  The church is no more organized on egalitarian principles than the family.  And we know what the bible says about families and headship.

The functions of the divinely ordained gifts of ministry reflect the headship of Jesus Christ, that is what 1 Cor 11 is talking about -- HOW that headship is reflected in the family and in the church.  Adventist theology and practice has always recognized reflected headship in Christ.  Our structure screams it out - its obvious.
