Symbols are an important part of Reformed worship. We use light and darkness, crosses, doves, shepherds and sheep to help us see God, who in Christ and through the Spirit is redeeming us. We do this because as Reformed Christians we believe that life and worship are one. A variety of media is appropriate in the Reformed worship service. Increasingly, wood and glass, architecture, inspiring banners, paintings, musical compositions, and liturgical dance are being used to touch our hearts and to help us sing God's praise.
