“Musical instruments in celebrating the praises of God would be no more suitable than the burning of incense, the lighting of lamps, and the restoration of the other shadows of the law. The Papists therefore, have foolishly borrowed, this, as well as many other things, from the Jews. Men who are fond of outward pomp may delight in that noise; but the simplicity which God recommends to us by the apostles is far more pleasing to him. Paul allows us to bless God in the public assembly of the saints, only in a known tongue (1 Corinthians 14:16) What shall we then say of chanting, which fills the ears with nothing but an empty sound?”

“Then let us not think that this Law is a special Law for the Jews; but let us understand that God intended to deliver us a general rule, to which we must yield ourselves. Since, it is so, it is to be concluded, not only that it is lawful for all kings and magistrates, to punish heretics and such as have perverted the pure truth; but also that they be bound to do it, and that they misbehave themselves towards God, if they suffer errors to rest without redress, and employ not their whole power to shew greater zeal in their behalf than in all other things.”

“This is why Paul upholds the teaching of the gospel in such a forceful way ... Seeing such an example and such a picture of man’s great weakness and fickleness, Paul states that the truth of the gospel must supersede anything that we may devise … he is showing us that we ought to know the substance of the doctrine which is brought to us in the name of God, so that our faith can be fully grounded upon it. Then we will not be tossed about with every wind, nor will we wander about aimlessly, changing our opinions a hundred times a day; we will persist in this doctrine until the end. This, in brief, is what we must remember.”

“Were the judgments of mankind correct, custom would be regulated by the good. But it is often far otherwise in point of fact; for, whatever the many are seen to do, forthwith obtains the force of custom. But human affairs have scarcely ever been so happily constituted as that the better course pleased the greater number. Hence the private vices of the multitude have generally resulted in public error, or rather that common consent in vice which these worthy men would have to be law.”

“Instrumental music was only tolerated, on account of the times and of the people. But in gospel times, we must not have recourse to these, unless we wish to destroy the evangelical perfection, and to obscure the meridian light, which we enjoy in Christ our Lord.”

“The Lord commands us to do good unto all men without exception, though the majority are very undeserving when judged according to their own merits... [The Scripture] teaches us that we must not think of man's real value, but only of his creation in the image of God to which we owe all possible honor and love.”

“John Calvin, Comment on 2 Cor. 5:20This is why Paul upholds the teaching of the gospel in such a forceful way ... Seeing such an example and such a picture of man’s great weakness and fickleness, Paul states that the truth of the gospel must supersede anything that we may devise … he is showing us that we ought to know the substance of the doctrine which is brought to us in the name of God, so that our faith can be fully grounded upon it. Then we will not be tossed about with every wind, nor will we wander about aimlessly, changing our opinions a hundred times a day; we will persist in this doctrine until the end. This, in brief, is what we must remember.”
