Ceremony Program Thank You Wording How Do You Write A Catholic Wedding Program If You Have Two Priests On Altar - One Main Officiant & Assistant?

How do you write a Catholic wedding program if you have two priests on altar - one main officiant & assistant? - ceremony program thank you wording

I get in a few weeks (Catholic Church married). Basically, a manager and another incumbent priests (who in the community is moving til) also - I've spoken with the principal celebrant and is happy, another priest at the altar as well have. My question really is, as in the main text of the ceremony, because there are two priests. Officiant basic idea but not sure how to call another priest? Thank you!
