New York: After 40 years of praying in exactly the same way, English-speaking Catholics around the world had a challenge waiting for them when they turned up to Mass.

The Mass liturgy, or the text of the most sacred Roman Catholic rite, has been re-launched across the English- speaking world to comply with the Vatican's wish for a more traditional and spiritual tone.

At Saint Monica's, an impressive neo-Gothic church in New York City, parishioners clearly struggled to adapt to the discreet shifts in language laid out on a neatly printed pamphlet.

For decades, when the priest declared, "The Lord be with you," the congregation would reply: "And also with you." This was so ingrained that although the pamphlet instructed in bold that the response was now, "And with your spirit," few managed to make the switch.

Priests, who have far more to say during Mass and know their parts by heart, were having to tiptoe through the texts.

"It will probably take four weeks for the priests to get used to the rhythm," Monsignor Thomas Modugno said afterwards. "It's easier for the people. It's hard for us priests: you get distracted for a moment and automatically you go back to the old version."

The new wording reflects years of work and negotiation involving English-majority Catholic communities from the US to Europe and Africa to Asia.

Changes are frequent, but small, rather than structural. There is nothing on the scale of the revolution brought by the Vatican's abandonment in the 1960s of the centuries-old Latin Mass.

However, church officials say they want to restore some of the linguistic spirit of that old Mass by tweaking the English translation to reflect more accurately the meanings and cadences of the ancient Latin language.
The results have been criticized by some Catholics as unnecessarily archaic-sounding and confusing.

The news site quoted one outspoken bishop, Donald Trautman from Pennsylvania, complaining that the alternations introduce a "jumble of subordinate clauses" that threaten "pastoral disaster."

In the previous version of the Nicene Creed, a key prayer for Catholics, Jesus was described as "begotten, not made, one in Being with the Father." Now he is "begotten, not made, consubstantial with the Father."

The word "consubstantial" has come in for particular ridicule from critics, but church leaders say it precisely describes the mystical link between Jesus and the Father within the Trinity.
