I am this year's coordinator for a local observance of an annual event held by my alma mater. The event is called Muster, the school Texas A&M University. The local group is my classmates. Traditionally the coordinator closes the ceremony with the exact same words, year to year. The final sentence is: "The Muster is dismissed until April 21, 20xx, and may God be with us all until we meet again."
If you were in my position, what would you do?
"The Muster is dismissed until April 21, 20xx. Until we meet again."
You don't have to say 'god'. If they don't like it, they don't have to ask you to be the
coordinator again. If anyone asks why you didn't say it that, tell them. Do not allow
yourself to be coerced into speaking words you don't believe.
Wow.... The closest I'd wilingly come is to change the words to "may your god be with you until we meet again." In my mind that is a recdognition of different religious traditions as well as slyly lettign those who don't believe have not god, as well as slyly stting that you don't believe in god.
