CiW Lectionary - Year B - Weekdays I
A lectionary is a pattern for Bible readings for the Church year. This means that churches in the Church in Wales are able to use the same readings on any given day.
Liturgy is a set form of words and action used for worship. In the Church in Wales (and many other churches) these forms follow the same pattern from one congregation to another. Most Anglican liturgies look back in some way to the Book of Common Prayer.
