I missed the delegate's statement. If he or she was implying that Flag/General Officer selection is biased against LCMS, he or she is wrong. As far as FO/GO selection being different, that is also wrong.
There are only a few chaplain FOs/GOs at a time. Army, Navy and Air Force active duty each have one 2-star and one 1-star. The reserve components (Army, AF, Navy, Nat Guard) each have one 1-star. That makes a total of 10 chaplain FOs/GOs at a given time (6 active, 4 reserve). That is out of thousands of chaplains in the system.
FOs/GOs are board selected just like any other officer. The majority of the board are not chaplains but other FOs/GOs. A zone is established based upon date of rank to O-6 (Captain or Colonel) and all chaplains within the zone are considered equally. Only one will be selected. The denomination of the chaplains is not known or considered.
My predecessor was a very conservative Presbyterian. My successor will be a very conservative Baptist. Both my predecessor and my successor are model chaplains who have firm faith commitments and the ability to facilitate freedom of religion for all military personnel. The next one to be selected in three years may or may not be conservative but will be charged with the same responsibility.
There are increasing challenges to the free exercise of religion in the United States. The military will reflect those challenges as a part of American society.
