Finding reasons for mitzvot

Hi,

Here's another challenging statement from R' Moshe Sofer, aka Chatam Sofer:

"The deviant members of our people attempt to give a reason for every commandment in the Torah. On account of this the Torah will fade away, for they will say that once the reason is invalidated, so, too, is the commandment."

(Derashot Chatam Sofer 1:19a)

Have a great day,
Mordechai
