THE SECOND COMMANDMENT
You shall not take the name of the Lord your God in vain.72
You have heard that it was said to the men of old, "You shall not swear falsely. . But I say to you, Do not swear at all. (Mt.5:33)
* I. THE NAME OF THE LORD IS HOLY
2142 The second commandment prescribes respect for the Lord's name. Like the first commandment, it belongs to the virtue of religion and more particularly it governs our use of speech in sacred matters.
2143 Among all the words of Revelation, there is one which is unique: the revealed name of God. God confides his name to those who believe in him; he reveals himself to them in his personal mystery. The gift of a name belongs to the order of trust and intimacy. "The Lord's name is holy." For this reason man must not abuse it. He must keep it in mind in silent, loving adoration. He will not introduce it into his own speech except to bless, praise, and glorify it.74
2144 Respect for his name is an expression of the respect owed to the mystery of God himself and to the whole sacred reality it evokes. The sense of the sacred is part of the virtue of religion:
"Are these feelings of fear and awe Christian feelings or not? . . . I say this, then, which I think no one can reasonably dispute. They are the class of feelings we should have - yes, have to an intense degree - if we literally had the sight of Almighty God; therefore they are the class of feelings which we shall have, if we realize His presence. In proportion as we believe that He is present, we shall have them; and not to have them, is not to realize, not to believe that He is present."--John Henry Cardinal Newman
2145 The faithful should bear witness to the Lord's name by confessing the faith without giving way to fear.76 Preaching and catechizing should be permeated with adoration and respect for the name of our Lord Jesus Christ.
