Liturgy, or order of worship, is important in the RCA. Therefore, the RCA has a fixed Liturgy and other liturgies.
The fixed Liturgy applies primarily to the sacraments, and it also provides flexibility for local consistories to guide the worship of their congregations using orders of worship that have been generated for occasional or local use. The Liturgy is our “common prayer”: it declares what the church has agreed to say in the same way as it gathers for worship.
