John Calvin,
Calvin's Commentaries—Complete…
“ Truly frivolous is their boasts that their magical exorcisms stand in the place of the word. For nothing can be called a covenants but what is perceived by us to be clearly revealed, so that it may edify our faith; these actors, who by gesture alone, or by a confused murmuring, play as on pipes, have nothing like this.We now consider how the covenant is rightly kept; namely, when the word precedes, and we embrace the sign as a testimony and pledge of grace; for as God binds himself to keep the promise given to us; so the consent of faith and of obedience is demanded from us. ”
