Commenting on Rev 20:10a:
This mountain is Christ.
The Prophet speaks of this mountain, saying: “In the last days, the mountain of
the house of the Lord shall be established above the tops of the mountains”
(Isa. 2:2). The mountains above whose tops the mountain of the house of the
Lord is said to be established signify the Fathers of the Old Testament.
Therefore the mountain of the house of the Lord is said to be established above
their tops because they themselves foretold him, and when he came in the flesh,
he surpassed them by a wondrous height. Therefore the house of the Lord, that
is, the Church, was built upon this mountain, because it was founded upon
Christ, as the Apostle Paul says: “For no one can lay any foundation other than
the one already laid, which is Jesus Christ” (1 Cor. 3:11). (Commentary on
Revelation by Berengaudus of Ferrières [trans. John Litteral; 2026], 345)
