Revere is Holy Name

Pillar Focus The Commandments "You shall not take the name of the Lord your God in vain"

From the Compendium of the Catechism of the Catholic Church:

447. How does one respect the holiness of the Name of God?
One shows respect for the holy Name of God by blessing it, praising it and glorifying it. It is forbidden, therefore, to call on the Name of God to justify a crime. It is also wrong to use the holy Name of God in any improper way as in blasphemy (which by its nature is a grave sin), curses, and unfaithfulness to promises made in the Name of God.

448. Why is a false oath forbidden?
It is forbidden because one calls upon God who is truth itself to be the witness to a lie.
“Do not swear, whether by the Creator or by any creature, except truthfully, of necessity and with reverence.” (Saint Ignatius of Loyola)
449. What is perjury?
Perjury is to make a promise under oath with the intention of not keeping it or to violate a promise made under oath. It is a grave sin against God who is always faithful to his promises.
