CHICAGO (CBS) — Starting this Sunday, Roman Catholics in the United States and throughout the rest of the English-speaking world will find that mass has changed somewhat.

For the first time in about 40 years, the Catholic Church is changing some of the wording it uses in prayers and responses said at mass.

The most notable change will be whenever the priest says “The Lord Be With You.”

Until Sunday, the response has been, “and also with you,” but starting Sunday, the response will be, “And also with your spirit.”

There are many other wording changes too, all part of what the Catholic Church says is a better English interpretation of the Latin mass.

Fr. Jerry Gunderson, pastor of Mary, Seat of Wisdom Church in Park Ridge, says he already has had some feedback from some of his parishioners when they practiced the new wording.

He says they said, “this isn’t so bad” and “this isn’t as major as I thought it was going to be.”

Most parishes have been preparing their parishioners for months with information sessions and distribution of placards with the new wording on them.

Gunderson sees the changes in wording for the people in the pews as “relatively minor.” He says the wording used by the priests has changed significantly more.
