Prior to the 1960s, the Christian Reformed Church (CRC) practiced a form of worship drawn from its Reformation heritage, which entailed a calendar of observances distinct from the traditional Christian year. In the 1960s, liturgical renewal in the CRC coincided with the worship reforms of Vatican II, leading to the widespread recovery of the Christian year in the CRC. However, many congregations still worship in accordance with the traditional Reformed pattern. Other congregations that have adopted a praise-and-worship style recognize major Christian holidays but do not adhere to the church calendar.
The RCA originally sang from the Genevan Psalter but in subsequent years adopted music and hymn resources from other denominations. More recently it has published its own hymnbook and musical resources. However, some churches have adopted the praise-and-worship songs and have abandoned the hymnal.
