The point before us is one of vast importance. Let us lay hold upon it firmly, and never let it go. It is the very point on which our Reformers had their sharpest controversy with the Romanists, and went to the stake, rather than give way. Sooner than admit that the Lord's Supper was a sacrifice, they cheerfully laid down their lives. To bring back the doctrine of the "real presence," and to turn the good old English communion into the Romish "mass," is to pour contempt on our Martyrs, and to upset the first principles of the Protestant Reformation. Nay, rather, it is to ignore the plain teaching of God's Word, and do dishonour to the priestly office of our Lord Jesus Christ. The Bible teaches expressly that the Lord's Supper was ordained to be "a remembrance of Christ's body and blood," and not an offering. The Bible teaches that Christ's vicarious death on the cross was the one perfect sacrifice for sin, which never needs to be repeated. Let us stand fast in these two great principles of the Christian faith. A clear view of the intention of the Lord's Supper is one of the soul's best safeguards against the delusions of modern days. II. In the second place, let me try to show _who ought to be communicants_? _What kind of persons were meant to go to the Table and receive the Lord's Supper?_ It will clear the ground if I first show who ought not to be partakers of this ordinance. The ignorance which prevails on this, as well as on every part of the subject, is vast, lamentable, and appalling. If I can contribute anything that may throw light upon it, I shall feel very thankful. The principal giants whom John Bunyan describes, in "Pilgrim's Progress," as dangerous to Christian pilgrims, were two, Pope and Pagan. If the good old Puritan had foreseen the times we live in, he would have said something about the giant Ignorance.
