The sum is, that the worship of God must be spiritual, in order that it may correspond with His nature. For although Moses only speaks of idolatry, yet there is no doubt but that by synecdoche, as in all the rest of the law, he condemns all fictitious services which men in their ingenuity have invented.
John CalvinWherever 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 CalvinAt this day . . . the earth sustains on her bosom many monster minds, minds which are not afraid to employ the seed of Deity deposited in human nature as a means of suppressing the name of God. Can anything be more detestable than this madness in man, who, finding God a hundred times both in his body and his soul, makes his excellence in this respect a pretext for denying that there is a God? He will not say that chance has made him different from the brutes; . . . but, substituting Nature as the architect of the universe, he suppresses the name of God.
John CalvinTo know God as the sovereign disposer of all good, inviting us to present our requests, and yet not to approach or ask of him, were so far from availing us, that it were just as if one told of a treasure were to allow it to remain buried in the ground.
John Calvin
