8. Arise, O Lord, into thy resting-place: thou and the ark which thou hast
sanctified. Once the prophet realised that the Lord Christ’s promises
previously mentioned had been fulfilled, he cried out to the Lord: Arise into thy resting-place, for he did
not wish any debt to remain unpaid. He sought to make clear the outcome of
events in the dispensation of the attained truth: in other words, that Christ
should rise again from the world below into the enduring blessedness of His
divinity. Observe that he added thy
resting-place; for Your own majesty bestowed it on You, since You reign with
the Father in equal power and everlasting glory. He did not wish you to think
that the Head could abandon the members, so he added: Thou and the ark which thou hast sanctified, in other words, “the
Church which You have deigned to sanctify by making it Your members.” He did
not specify the ark of Noah, or the ark of the covenant, though both of these
appeared to represent a type of the Church; instead he designated her in a special
way when he added: Which thou hast
sanctified. Now observe what follows. (Cassiodorus, Cassiodorus: Explanation
of the Psalms, 3 vols. [trans. P. G Walsh; Ancient Christian Writers
