Lutheran Librarian - Luther’s comments here on Psalm 12 are both historical and prescient.
“This is a prayer containing a heavy complaint against them, who, introduce human doctrines instead of the word of God, and who, afterwards, by various new traditions and forms of worship disturb the church, and fill all things with a white-wash show of religion, and with the outward daubing of Pharisaism and hypocrisy, so that wicked men and hypocrites reign on every side, as the last verse complains.
“For when human doctrines have once invaded the church, they go on to rage far and wide, and spread in all directions like a cancer; there is no end to their corruption and destructive influence; they take possession of all things and wonderfully vex and torment consciences: so that the number of the true saints and of those that truly fear God is few and small indeed: of this the infinite variety of papistical hypocrisy affords a manifest example.
