The liturgical churches follow a yearly pattern of worship called the Church Year or the Liturgical year. This is divided into various liturgical seasons: Advent, Christmas, Epiphany, Lent, Holy Week, Easter, Pentecost. Each season emphasizes appropriate lectionary readings. Click on the names of each of season to see an overview for that season.
The Liturgical Year closely follows the Jewish Calendar of Feast Days:
The Feast Days in the Jewish Calendar were not arrived at arbitrary. Those days were appointed by God in Holy Scripture. The most important of the Jewish Feasts were the three pilgrimage feasts appointed by God: Passover (Pesach), Feast of Weeks or Pentecost (Shavuot), and Tabernacles (Sukkot). Christian feast days correspond to these days: Our Easter is the Jewish Pesach and our Pentecost is the Jewish Shavuot. Christmas is our Sukkot. In fact, Easter and Pentecost are the prophetic fulfillment’s of their corresponding Jewish Feasts. (See Jewish Feasts.)
See Liturgical Calendar for a detailed look at the lectionary readings for all Sundays and Holy Days for the current year and subsequent years.
