Q: As an addendum to your post https://paulturner.org/deacon-wearing-a-stole/, Ceremonial of Bishops §36 says “Within a celebration a master of ceremonies who is an ordained deacon may wear a dalmatic and the other diaconal vestments.”

A: Thank you for that reference. A deacon emcee has a choice then: vest in cassock and surplice, or vest in alb, stole and dalmatic. Even CB 36 does not envision a deacon emcee adding a stole at communion time. To me, this presumes he chooses a vesture and wears it throughout.
