The Leaf And The Word

Et folium ejus non decidet Id est sermo ipsius nullo casu a veritate discedit, sed tanquam in arbore palmae folia manentia sunt, ita et ista infixa veritati certis promissionibus perserverant, sicut in Evangelio legitur: Caelum et terra transibunt, verba autem mea non praeteribunt. Et intuere Domini verba foliis arboris comparata, quia sicut illa fructus tegunt, sic promissiones suas et ista custodiunt. Hae sunt aquae spirituales, haec folia salutaria, de quibus in Apocalypsi beatus Joannes dicit: Et ostendit mihi flumen aquae vivae splendidum, tanquam crystallum, exiens de throne Dei et Agni; in medio plateae ejus, et ex utraque parte fluminis, arborem vitae, quae facti fructum duodecies, singulis mensibus reddens fructum suum, et folia arboris illius sunt ad sanitatem genitum deputata. Cassiodorus, Expositio In Psalterium, Psalmus I Source: Migne PG 70.31b-c

And its leaf does not fall... 1 That is, His word does not in any way fall from the truth, but as the leaves of the palm tree remain, so these rooted in the firm promises of truth perservere, as it is said in the Gospel: 'Heaven and earth shall pass away, but my words shall not pass away.' 2 And see that the words of the Lord are compared to the leaves of a tree, because as they cover the fruit, so even they guard His promises. These are the spiritual waters and these are the leaves of salvation concerning which the blessed John says in the Apocalypse: 'And he showed to me the glittering river of the waters of life, like crystal, coming forth from the throne of God and the lamb, and in the midst of the way, on both sides of the river, the tree of life, bearing its fruit twelvefold, and giving its yield monthly, and the leaves of the tree give health to all the peoples.' 3 Cassiodorus, Commentary On The Psalms, Psalm 1 1 Ps 1.5 2 Mt 24.15 3 Apoc 22.1-2
