Catena Aurea · Johannesevangelium 1
In him was life. (Vulg. quod factum est in ipso vita erat.) And the life was the light of men.
(in Joh. tr. 1. c. 18) Life of itself gives illumination to men, but to cattle not: for they have not rational souls, by which to discern wisdom: whereas man, being made in the image of God, has a rational soul, by which he can discern wisdom. Hence that life, by which all things are made, is light, not however of all animals whatsoever, but of men.
