If physical matter collapse, namely if material human bodies break to separate corpuscular particles, then corporal forms of wave matter are kept. Therefore it is possible to recreate bodies by means of reunion of waves with corpuscles of global matter.
But if waves of physical matter collapse then bodies of people disappear and are not kept.
Recreation of physical bodies is the basic postulate of Christian creed, and consequently it is possible to trust that christening is the condition of preservation and future reconstruction or resurrection of dead people in the material world.
