The extent to which congregations in the Reformed Church in America (RCA) practice the church year varies widely. A few churches observe only Christmas, Easter, and Palm Sunday. More than 80 percent keep Advent, Lent, Maundy Thursday, and Pentecost. About three-quarters observe Good Friday, around 40 percent celebrate Epiphany, Ascension, and Ash Wednesday, and almost a quarter mark Trinity Sunday.
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.
