The first thing in religion is, to state the Object of it right, and to acknowledge and receive it for such. This, I confess, is the intent of this First Precept of the Law, which is therefore the basis and foundation that bears the weight of all the rest. And therefore, as we said before, though the preface looks to them all, yet it looks first to this which is nearest it, and is knit with it, and through it to all the rest. The preface asserted God’s authority as the strength of His law, and this First Precept commands the acknowledgment and embracing of that His authority, and His alone, as God. And this is the spring of our obedience to all His commandments.
Robert Leighton (Archbishop of Glasgow, 1611 – 1684)
