Refer to Church Fathers re: formalization of ‘morning and evening’ prayers)
‘Fixed hours’ became formalized across Church history
“In the course of time other hours were also sanctified by communal prayer, hours which the Fathers judged were found in the Acts of the Apostles.” (See, General Introduction to the Liturgy of the Hours p. 1)
Monastic vs. Congregational Prayers
As the monastic prayers continued to develop, it became its own “office” or duty throughout the day to be held by the Church ‘officials’
A fulfillment of the command to ‘pray without ceasing’
Domestic Prayer
The prayer of the Church within the ‘domas’ (household) of faith
Of course, this draws together a sense of priesthood of all believers as well as the sense of the scattered ‘household’ of faith
Note, again, the resurgence of the LOH during the Ecumenical and Liturgical movements of the 19th Century
