We should never insult others on account of their faults, for it is our duty to show charity and respect to everyone.
There are people who are known to be very liberal, yet they never give without scolding or pride or even insolence.
When a member of our physical body is diseased and the whole body has to labor to restore it to health, we do not despise this diseased member or hold it under obligation because it needs all this assistance.
