8. Now in things that are moral commands, the law hath received no change: but in things sacramental and ceremonial its outward form is altered: yet not one of the mystical significations is done away: for the law is not done away. Though the 'priesthood being changed, there is made of necessity a change likewise of the law.' [Footnote 102] [Footnote 102: Hebrews vii, 12.] 9. Now, in Holy Scriptures there be divers senses: as historic, allegoric, tropologic, and anagogic. Whence, according to Boethius, all divine authority ariseth from a sense either historical or allegorical or from both. And according to S. Hierom, we ought to study Holy Scriptures in three ways:--firstly, according to the letter; secondly, after the allegory, that is, the spiritual meaning; thirdly, according to the blessedness of the future. {6} History is _things signified by words:_ as when a plain relation is made how certain events took place: as when the children of Israel, after their deliverance from Egypt, made a tabernacle to the Lord. And history is derived from [Greek text], which is to gesticulate: [Footnote 103] whence gesticulators (that is, players) are called _histriones_. [Footnote 103: Here is a notable instance of Durandus's misderivations, of which we have spoken in the Introduction.] 10. Allegory is when one thing is said and another meant: as when by one deed another is intended: which other thing, if it be visible, the whole is simply an allegory, if invisible and heavenly, an _anagoge_. Also an allegory is when one state of things is described by another: as when the patience of Christ, and the sacraments of the Church are set forth by mystical words or deeds. As in that place: 'There shall come forth a rod of the stem of Jesse, and a branch shall grow out of his roots:' [Footnote 104] which is in plain language. The Virgin Mary shall be born of the family of David, who was the son of Jesse. [This is an example of mysticism in words.] Truth is also set forth by mystic deeds: as the children of Israel's freedom from Egyptian slavery, wrought by the blood of a lamb, signifieth that the Church is freed by the Passion of Christ from demoniacal servitude. [Footnote 105] The word allegory is derived from the Greek _allon_, which means _foreign_, and _gore_, which is _sense_; that is, a _foreign sense_. [Footnote 104: Isaiah xi, 1.] [Footnote 105: See Appendix I.] {7}
