OHC 257.3
(Our High Calling 257.3)
The pure truth, which sanctifies the soul, will give you courage to cut yourself loose from the most pleasing acquaintance whom you know does not love and fear God, and knows nothing of the principles of true righteousness. We may always bear with a friend′s infirmities and with his ignorance, but never with his vices. Never marry an unbeliever. (OHC 257.3) MC VC
