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. |
| 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:
|
| 2145 The faithful should bear witness to the Lord's name by confessing the faith without giving way to fear. Preaching and catechizing should be permeated with adoration and respect for the name of our Lord Jesus Christ. |
| 2146 The second commandment forbids the abuse of God's name, i.e., every improper use of the names of God, Jesus Christ, but also of the Virgin Mary and all the saints. |
