Generally, a person who speaks loshon hora does so from a
somewhat smug and haughty perspective. Such a person, says the Chofetz Chaim, shows himself to be conceited, because by speaking as he does, he apparently sees himself as faultless. If he were truly aware of his faults, he would be reluctant to speak badly of others, for perhaps his own faults are greater.
The Chofetz Chaim tells us that one who speaks loshon hora
in a conceited way violates the commandment, Be careful lest you forget
Hashem your G-d (Devarim 8:11), which prohibits us from acting
arrogantly. Arrogance has particularly severe consequences because it is singled out as a trait which Hashem especially disdains. The Chofetz Chaim adds that if the speaker of loshon hora raises his own stature in peoples eyes by degrading his victim his offense is even more severe.
The Chofetz Chaim identifies another sin that one commits when
speaking loshon hora. Although transgressing any Torah prohibition is serious, this transgression goes to the heart of a Jews purpose in this world, which is to serve Hashem and bring the rest of the world to recognize Hashems greatness. The Torah warns us: You shall not desecrate My Holy
Name (Vayikra 22:32). At all times a Jew must be on guard that his
words or behavior not constitute a chillul Hashem (desecration of Hashems Name).
How is loshon hora a chillul Hashem?
The Chofetz Chaim explains that when a person speaks loshon
hora, it is not because he is lured by some physical enjoyment. Rather than succumbing to earthly temptation, he is merely casting off the restraints of Hashems Torah. It is as if he is making a statement: I understand
that Hashem commanded me to refrain from loshon hora, but according to my own priorities, it is just not that important.
Here is a mortal human being asserting his own priorities over those of the Master of the Universe. He basks in his own glory when he should be humbling himself. He desecrates Hashems name when he should be
sanctifying it. It is crystal clear then that when a person follows this path, he negates his mission as a Jew in this world.
