The things of divinity not only concern ministers, but are of infinite importance to all Christians. It is not with the doctrines of divinity as it is with the doctrines of philosophy and other sciences. These last are generally speculative points, which are of little concern in human life; and it very little alters the case as to our temporal or spiritual interests, whether we know them or not. Philosophers differ about them, some being of one opinion, and others of another. And while they are engaged in warm disputes about them, others may well leave them to dispute among themselves, without troubling their heads much about them; it being of little concern to them whether the one or the other be in the right.
But it is not thus in matters of divinity. The doctrines of this nearly concern everyone. They are about those things which relate to every man's eternal salvation and happiness.
