On Sundays and ferias, the DOL provides three readings to be distributed between MP and EP. If four are desired, an OT reading (in parentheses) is provided at Evening Prayer, taken from the alternate year (see BAS, page 450). Many use a non-scriptural reading for the fourth reading in the offices. On Saint’s days these may be taken from FAS. There are many other devotional volumes of non-scriptural readings available. Two of the more commonly used ones are Celebrating the Saints and Celebrating the Seasons both published by Canterbury Press.
