As we are treating of images and their worship, let us draw out the meaning more accurately and say in the first place what an image is; (2) Why the image was made; (3) How many kinds of images there are; (4) What may be expressed by an image, and what may not; (5) Who first made images. Again, as to worship: (1) What is worship; (2) How many kinds of worship there are; (3) What are the things worshipped in Scripture; (4) That all worship is for God, who is worshipful by nature; (5) That honour shown to the image is given to the original. 1st Point.—_What is an Image?_ An image is a likeness and representation of some one, containing in itself the person who is imaged. The image is not wont to be an exact reproduction of the original. The image is one thing, the person represented another; a difference is generally perceptible, because the subject of each is the same. For instance, the image of a man may give his bodily form, but not his mental powers. It has no life, nor does it speak or feel or move. A son being the natural image of his father is somewhat different from him, for he is a son, not a father. 2nd Point.—_For what purpose the Image is made._ Every image is a revelation and representation of something hidden. For instance, man has not a clear knowledge of what is invisible, the spirit being veiled to the body, nor of future things, nor of things apart and distant, because he is circumscribed by place and time. The image was devised for greater knowledge, and for the manifestation and popularising of secret things, as a pure benefit and help to salvation, so that by showing things and making them known, we may arrive at the hidden ones, desire and emulate what is good, shun and hate what is evil. 3rd Point.—_How many kinds of Images there are._
