There are three general Characters whereby we may know any Word to be the Word of God; and a Religion to be the true Religion. 1. That which doth most set forth the glory of God. 2. That which doth direct us to a rule which is a perfect rule of holinesse toward God, and righteousnesse to men. 3. That which shows us a means suitable to God’s glory and men’s necessity, to reconcile us to God. The word of God sets forth God’s glory in all the perfections, and is a compleat rule.
Leigh, Body of Divinity, quoted in Richard A. Muller, Post-Reformation Reformed Dogmatics, vol. I, 435.
