Catechesis: Second Commandment

To confuse the devil, I say, we should always have this holy name in our mouth, so that the devil may not be able to injure us as he wishes. It is also useful that we form the habit of daily commending ourselves to God, with soul and body, wife, children, servants, and all we have, against every need that may arise. So also the blessing and thanksgiving at meals and other prayers, morning and evening, have begun and remained in use.—LC I:72, 73
