The OCB Liturgical Manual was a natural outgrowth of the practice of attending morning and evening services every day according to the tradition of a different faith. On Wednesdays, which were defined as Honorary Sabbaths for the duration of the exercise, delegates were allowed to worship as they chose in the mornings, but in the evenings all attended an ecumenical service, for which an everchanging committee was responsible.
The more elaborate and irksome liturgies and rituals together with the difficulty of administering some of them, brought the advantages of "harmonizing" the best practices. The Liturgical Manual, faithfully records the various peculiar modes of worship practiced by the faiths represented in the CET, and supplies several model ecumenical liturgies and endorses those considered most suitable for constituting a complete program of devotions for the whole year.
