Who does what? When neither know their role.
Who carries the Gospel in?
Who leads the Prayer of the Faithful?
Who receives the Gifts and prepares the Altar?
In our parish it is a great confusion, and obvious disregard for the Instructions in the Roman Missal. Power may be at the heart.

A: The deacon carries the Book of the Gospels.
The deacon lists the intentions in the prayer of the faithful.
Both priest and deacon may receive the gifts, though the deacon prepares the altar.
Sorry to hear about the confusion and disregard in your parish. In my experience, priests and deacons mean well, but do not always know the expected details.
