No matter what language you say (or sing) it in.
A person attending the recent mass at Chesire for novices to profess tells us:
Prayers of the Faithful as written in the program for the Mass:
"3. Preserve and increase the love of Christ and the spirit of the Founder in all religious families consecrated to you, and in a special way in the Legion of Christ."
Now I'm not sure if this was omitted or not because the petitions were sung in Latin and I didn't notice the text until later but the fact remains that the founder is still in the program for this Mass.
