Magistrates, who should know theology and should have the law before their eyes (Deut. 17:18–20; Josh. 1:8; Psalm 19), prescribe it for their subordinates (2 Chron. 17:7–9; Josh. 24:14ff.), protect it against enemies, as nursing fathers of the church (Isa. 49:23; 60:16) and as guardians of both tables of the law, and propagate it (Gen. 18:19).147 In sum they should, in all these ways, kiss Christ (Ps. 2:10–12), so that their polity becomes a theocracy, that is, a Christocracy.
