Liturgical Reader/Lector: read Scriptures during service, and is a great way to get involved! Readers are on a monthly rotation.
Altar Guild: the altar guild is responsible for preparing the vestments, setting up the sanctuary for the priests, and arranging the flowers. They prepare a space for our worship.
LEM (or Lay Eucharistic Ministry): the LEMs are responsible for helping set up and share the Eucharist during the service.
Email rector[at]stmarysdorchester.org to get involved, or ask someone serving when you come on Sunday who is in charge.
