A remarkable display of your usual impeccable writing, John.
Gnu: "Ordinance" is a Protestant Christian term for baptism, communion and other religious rituals. Some Protestants do not call them sacraments because they believe these rituals are outward expressions of faith, rather than impartations of God's grace. Also means rules passed by such as a town council, etc. "Ordnance" means military weapons and equipment, as in: "The ordnance was stored in bunkers near the airfield".
