Canon Quotes - page 2
In the interpretation of figurative passages, let the following canon be observed. If the passage be preceptive, either forbidding some flagitious deed and some heinous crime, or commanding something useful and beneficent: then such passage is not figurative. But, if the passage seems, either to command some flagitious deed and some heinous crime, or to forbid something useful and beneficent: then such passage is figurative. Thus, for example, Christ says: Unless ye shall eat the flesh of the Son of man, and drink his blood; ye shall have no life in you. Now, in these words, he seems to command a heinous crime or a flagitious deed. Therefore the passage is a figure, enjoining us to communicate in the passion of our Lord, and admonishing us to lay it up sweetly and usefully in our memory because, for us, his flesh was crucified and wounded. On the other hand, Scripture says: If thy enemy shall hunger, give him food; if he shall thirst, give him drink.
