Turn away from hypocrisy and evildoing
There are two ways of teaching and of power, the one of light and the other of darkness; and there is a great difference between the two ways… But the way of the Black One is crooked and full of a curse. For it is a way of eternal death with punishment wherein are the things that destroy men's souls--idolatry, boldness, exhalation of power, hypocrisy, doubleness of heart, adultery, murder, plundering, pride, transgression, treachery, malice…, covetousness, absence of the fear of God; persecutors of good men, hating the truth…, paying no heed to the widow and the orphan…, not pitying the poor man…, oppressing him that is afflicted…
It is good therefore to learn the ordinances of the Lord, as many as have been written above, and to walk in them. For he that does these things shall be glorified in the kingdom of God; whereas he that chooses their opposites shall perish together with his works. For this cause is the resurrection, for this the recompense. I entreat you: keep amongst you those to whom you may do good. Fail not.
St. Thomas Aquinas
