Commissioning of Liturgical Ministers On Sunday, February 23, we will commission those in our parish who serve the assembly that gathers for worship as liturgical ministers: ushers and greeters; lectors; cantors and musicians; extraordinary ministers of Holy of Communion; Mass coordinators; art and environment; sacristans, altar servers, and linen care. Let us both recognize their special role in contributing to our worship experience at St. Nicholas and St. William Parish.
