Institutes of the Christian Religion (2 Volume Set)

by John Calvin

There is one vow common to all believers, which taken in baptism we confirm, and as it were sanction, by our Catechism,5 8 17 and partaking of the Lord’s Supper. For the sacraments are a kind of mutual contracts by which the Lord conveys his mercy to us, and by it eternal life, while we in our turn promise him obedience. The formula, or at least substance, of the vow is, That renouncing Satan we bind ourselves to the service of God, to obey his holy commands, and no longer follow the depraved desires of our flesh. It cannot be doubted that this vow, which is sanctioned by Scripture, nay, is exacted from all the children of God, is holy and salutary. There is nothing against this in the fact, that no man in this life yields that perfect obedience to the law which God requires of us. This stipulation being included in the covenant of grace, comprehending forgiveness of sins and the spirit of holiness, the promise which we there make is combined both with entreaty for pardon and petition for assistance.
