62 As for toil, his whole life and not merely his writings afford the best example. Postumianus, who spent six months with him at Bethlehem, says: "He is wholly occupied in reading and with books; he rests neither day nor night; he is always either reading or writing something." Jerome's love of the Church, too, shines out even in his Commentaries wherein he lets slip no opportunity for praising the Spouse of Christ: The choicest things of all the nations have come and the Lord's House is filled with glory: that is, "the Church of the Living God, the pillar and the ground of truth." . . . With jewels like these is the Church richer than ever was the synagogue; with these living stones is the House of God built up and eternal peace bestowed upon her. Come, let us go up to the Mount of the Lord: for we must needs go up if we would come to Christ and to the House of the God of Jacob, to the Church which is "the pillar and ground of truth." By the Lord's voice is the Church established upon the rock, and her hath the King brought into His chamber, to her by secret condescension hath He put forth His hand through the lattices.
