CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 2158–2161

2158 God calls each one by name. Everyone's name is sacred. The name is the icon of the person. It demands respect as a sign of the dignity of the one who bears it.
2159 The name one receives is a name for eternity. In the kingdom, the mysterious and unique character of each person marked with God's name will shine forth in splendor. "To him who conquers . . . I will give a white stone, with a new name written on the stone which no one knows except him who receives it." "Then I looked, and Lo, on Mount Zion stood the Lamb, and with him a hundred and forty- four thousand who had his name and his Father's name written on their foreheads."
2160 "O Lord, our Lord, how majestic is your name in all the earth" (Ps 8:1)!
2161 The second commandment enjoins respect for the Lord's name. The name of the Lord is holy.
