Evidence for the Origin of Daily Prayer
The early Christians continued the Jewish practice of praying at mealtimes and at set hours of the day. The Didachē, a primitive Christian manual of instruction, prescribes prayer three times a day; Clement of Alexandria and Origen in the third century refer to a similar custom in Egypt, as well as to prayer in the night. At the same period in North Africa, however, Tertullian and Cyprian describe a more extensive pattern of daily prayer.
