On August 8, 2008, Bishop Arthur J. Serratelli, chairman of the American bishops' "Committee on Divine Worship", announced a new directive from the Vatican regarding the use of the name of God in the sacred liturgy. Specifically, the word "Yahweh" may no longer be "used or pronounced" in songs and prayers during liturgical celebrations.

In fact, for most of the Church's 2,000-year history use of the name was prohibited in public worship, out of respect for the Divine Name, according to Catholic tradition.

After Second Vatican Council (1962–65), some songs and hymns had begun to use the Tetragrammaton, which caused the Vatican to issue a clarification that the Divine Name was not to be used. Hymnals with these hymns have since inserted the word "Lord God" or other two-syllable alternatives in the place of the Tetragrammaton.
