Fisher’s Catechism on the Westminster Shorter Catechism:
Q. 1. What are the leading sins forbidden in this commandment?
A. Idolatry and will-worship.
Q. 2. What is the idolatry here condemned?
A. The worshipping of God by images: “Thou shalt not make unto thee any graven image,” &c.
Q. 3. What is an image?
A. It is a statue, picture, or likeness of any creature whatever.
Q. 4. Is it lawful to have images or pictures of mere creatures?
A. Yes, provided they be only for ornament; or the design be merely historical, to transmit the memory of persons and their actions to posterity.
Q. 5. Can any image or representation be made of God?
A. No; it is absolutely impossible; he being an infinite, incomprehensible Spirit, Isa. 40:18 — “To whom will ye liken God? or, what likeness will ye compare unto him?” If we cannot delineate our own souls, much less the infinite God; Acts 17:29 — “We ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man’s device.”
Q. 6. What judgment should we form of those who have devised images of God, or of the persons of the adorable Trinity?
A. We should adjudge their practice to be both unlawful and abominable.
Q. 26. Are our forefathers to be blamed for pulling down altars, images, and other monuments of idolatry, from places of public worship at the Reformation?
A. No; they had Scripture precept and warrant for what they did, Num. 33:52, and Deut. 7:5 — “Ye shall destroy their altars, and break down their images, and cut down their groves, and burn their graven images with fire.”
