None are farther from the kingdom of heaven than self-righteous formalists, who are perhaps filled with pride at their own attainments, while they are wholly destitute of the Spirit of Christ, and are controlled by envy, jealousy, and love of praise and popularity. They belong to the class that John addressed as a generation of vipers, children of the wicked one. They serve the cause of Satan more effectively than the vilest profligate; for the latter does not disguise his true character; he appears what he really is. (TDG 197.4) MC VC
