The Clementine Homilies by Unknown
Chapter III.--|Behold What Indignation.|
|But not otherwise will you endure to undertake much care for your purification unless you be angry with yourselves, and chastise yourselves for those things with which, as unprofitable servants, you have been ensnared, consenting to your evil lusts, that you may be able to let in your righteous indignation upon your mind, as fire upon a fallow field. If, therefore, ye have not righteous fire, I mean indignation, against evil lusts, learn from what good things ye have been seduced, and by whom ye have been deceived, and for what punishment ye are prepared; and thus, your mind being sober, and kindled into indignation like fire by the teaching of Him who sent us, may be able to consume the evil things of lust. Believe me, that if you will, you can rectify all things.
