Flesh torn by beasts signifies things that bear the nature of death, and dogs signify unclean persons (Matt. 7:6 and note Matt. 7:62b; Phil. 3:2 and note Phil. 3:22c). This ordinance signifies that we should eat only Christ as our life supply, not anything of death. Cf. note Gen. 8:71 in Gen. 8 and note Lev. 11:311.
