Error must be uncovered in order that its nothingness may be recognized and it thereby be destroyed.

Unless people see where the evil is they cannot set to work to destroy it.

This uncovering -- however, -- has to be done lovingly, wisely, and at the proper time. And it must not be done until all feelings of antagonism or criticism have been entirely eliminated out of one's own thought, and tenderness and compassionate love entained.

Uncovering error does not mean simply pointing out the sin; it means pointing out its nothingness as well, so helping to destroy it.
