The Flower Guild is part of the altar service at St. Matthias. Members provide fresh flower arrangements each week for the Sunday worship service with the donations from members of the congregation to the glory of God. Members also provide sanctuary decorations for the special feast days of Christmas, Palm Sunday and Easter

Flower Guild members also enjoy occasional training days to learn new or better techniques for the art of flower arranging. Any member of the congregation of St. Matthias who is moved by the beauty of God's creation is welcome to join the Flower Guild at St. Matthias.
