OHC 256.2
(Our High Calling 256.2)
The Christian should withdraw himself from the company of those who are as a snare to his soul. When you come in contact with those whom you cannot lift into a pure and holy atmosphere, because their moral tastes are wholly perverted, you must shun their society. Persons of this class have generally a strong will and positive temperament, and when wrought upon by the enemy of God, they become efficient agents in leading souls from the path of righteousness to paths that are false and dangerous. The moral atmosphere surrounding these souls is tainted with evil, and exerts only a defiling influence. (OHC 256.2) MC VC
