The right to multiply or extend them, and the claim that they possess a saving efficacy, characterizes one great division of the professed Christian church, while those who are called Protestants and the Reformed, regard them chiefly as signs; though of these, some seem to have much of that appetency after undue reliance on forms which Paul seeks to correct in the Epistle to the Galatians, while others go to an opposite extreme, and undervalue the two divinely-appointed sacraments, which they think have no efficiency as used by the Spirit of God, but only as signs used by us to represent something.
Between these divisions of the Christian church lies the battle-ground of great ecclesiastical controversies from the beginning, as the Netherlands were, for a long time, the battle-field of Europe.
Archbishop Leighton seems to strike the balance between formalism and sacramental grace in ordinances, as well as any writer, in commenting on these words of Peter, "The like figure whereunto, even baptism, doth also now save us." He says: "Thus, then, we have a true account of the power of this, and so of other, sacraments, and a discovery of the error of two extremes.

(1.) Of those who ascribe too much to them, as if they wrought by a natural, inherent virtue, and carried grace in them inseparably.

(2.) Of those who ascribe too little to them, making them only signs and badges of our profession.

Signs they are, but more than signs merely representing; they are means exhibiting, and seals confirming, grace to the faithful.
But the working of faith and the conveying Christ into the soul, to be received by faith, is not a thing put into them to do of themselves, but still in the supreme hand that appointed them; and he indeed both causes the souls of his own to receive these his seals with faith, and makes them effectual to confirm that faith which receives them so.

They are then, in a word, neither empty signs to them who believe, nor effectual causes of grace to them that believe not." Let me make the distinction very clear to your mind, for it is of great practical importance.
