But when we speak of the dominion of the Mediator as spiritual, it is necessary to guard against supposing that it can have no sort of connection with the world, or with things that are secular. Such an idea it is not at all our intention to convey . . . Because the dominion of Christ is spiritual in its nature, to conclude that everything connected with his kingdom must be spiritual also, and that nothing earthly or secular can have any relation to it, is an inference alike illogical in reasoning and unsupported by fact.
