I have lived in two diocese recently. In both places I have volunteered to fill one of two Liturgical roles, Lector and Extraordinary Minister of Holy Communion.
In one Diocese I was told that each person could only be in one role during Mass. In the other I can be assigned to both roles during Mass.
Is there anything in the GIRM or Liturgical documents that uphold either one of these practices.
For me - I believe one person should only fulfill one role.
