Daily Devotions for
Families and Individuals

These devotions follow the basic structure of the Daily Office of the
Church.

When more than one person is present, the Reading and the Collect
should be read by one person, and the other parts said in unison, or in
some other convenient manner. (For suggestions about reading the
Psalms, see page 582.)

For convenience, appropriate Psalms, Readings, and Collects are
provided in each service. When desired, however, the Collect of the
Day, or any of the Collects appointed in the Daily Offices, may be used
instead.

The Psalms and Readings may be replaced by those appointed in

a) the Lectionary for Sundays, Holy Days, the Common of Saints, and
Various Occasions, page 888.

b) the Daily Office Lectionary, page 934

c) some other manual of devotion which provides daily selections for
the
Church Year.
