Origen, on Ps 18:1

“Unto the end. A psalm for David.”

“If someone, hypothetically, should seem to believe in Jesus but should not believe that the God of the law and of the gospel is one, whose glory the heavens declare, since they were made by him, and the work of whose hands the firmament proclaims, since it is their work, this person would be deficient in the greatest article of faith.”
