We have already stated the importance which we ought to attach to the ministry of the word and sacraments, and the extent to which our reverence for it ought to be carried, so as to account it a perpetual mark and characteristic of the Church. That is to say, that wherever _that_ exists entire and uncorrupted, no errors and irregularities of conduct form a sufficient reason for refusing the name of a Church. In the next place, that the ministry itself is not so far vitiated by smaller errors, as to be considered on that account less legitimate. It has further been shown, that the errors which are entitled to this forgiveness are those by which the grand doctrine of religion is not injured, which do not suppress the points in which all believers ought to agree as articles of faith, and which, in regard to the sacraments, neither abolish nor subvert the legitimate institution of their Author. But as soon as falsehood has made a breach in the fundamentals of religion, and the system of necessary doctrine is subverted, and the use of the sacraments fails, the certain consequence is the ruin of the Church, as there is an end of a man’s life when his throat is cut, or his heart is mortally wounded. And this is evident from the language of Paul, when he declares the Church to be “built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner-stone.”[781] If the foundation of the Church be the doctrine of the prophets and apostles, which enjoins believers to place their salvation in Christ alone, how can the edifice stand any longer, when that doctrine is taken away? The Church, therefore, must of necessity fall, where that system of religion is subverted which alone is able to sustain it. Besides, if the true Church be “the pillar and ground of truth,”[782] that certainly can be no Church where delusion and falsehood have usurped the dominion.
