Wherever we find the Word of God surely preached and heard, and the sacraments administered according to the institution of Christ, there, it is not to be doubted, is a church of God.
John CalvinSince no daily responses are given from heaven, and the Scriptures are the only record in which God has been pleased to consign His truth to perpetual remembrance, the full authority which they ought to possess with the faithful is not recognized unless they are believed to have come from heaven as directly as if God had been heard giving utterance to them.
John CalvinThe whole comes to this, that Christ, when he produces faith in us by the agency of his Spirit, at the same time ingrafts us into his body, that we may become partakers of all spiritual blessings.
