But may not images be tolerated in the churches, as books to the laity?

No: for we must not pretend to be wiser than God, who will have his people taught, not by dump images, (a) but by the lively preaching of his word. (b)

(a) Jer.10:8 But they are altogether brutish and foolish: the stock is a doctrine of vanities. Hab.2:18 What profiteth the graven image that the maker thereof hath graven it; the molten image, and a teacher of lies, that the maker of his work trusteth therein, to make dumb idols? Hab.2:19 Woe unto him that saith to the wood, Awake; to the dumb stone, Arise, it shall teach! Behold, it is laid over with gold and silver, and there is no breath at all in the midst of it. (b) Rom.10:14 How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher? Rom.10:15 And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things! Rom.10:17 So then faith cometh by hearing, and hearing by the word of God. 2 Pet.1:19 We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts: 2 Tim.3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: 2 Tim.3:17 That the man of God may be perfect, throughly furnished unto all good works.
