20. Shall not He take account of their toil, Who will not cast off for ever even those whom He casts off? For David says: “God will not cast off for ever,” Ps. lxxvii. [lxxvi.] 7. In the Psalm this passage is a question of the Psalmist in his bitter troubles, “Will God cast off?” St. Ambrose, in arguing against Novatian, not only modifies the text, but somewhat modifies its meaning. and in opposition to this shall we listen to heresy asserting, “He does cast off for ever”? David says: “God will not for ever cut off His mercy from generation to generation, nor will He forget to be merciful.” Ps. lxxvii. [lxxvi.] 8, 9. This is the prophet’s declaration, and there are those who would maintain a forgetfulness of mercy on God’s part.
