Today, July 11, is recognized by many in the Western Church as the feast day of
Benedict of Nursia. St. Benedict is widely acknowledged as the father of
Western monasticism and in large part is responsible for the form of prayer we
know as the liturgy of the hours. His commitment to pray the Psalms and other
prayers throughout the day left a lasting influence not only in monastic orders
but in the Catholic, Anglican, Orthodox, Lutheran, and other Protestant
traditions who sought a way to fulfill Paul's imperative to "pray without
ceasing." Within the Christian church, there is probably no greater commitment
to praying the Psalms than those who follow Benedict's example, even if they do
not realize they are doing so. If you would like to try praying the liturgy of
the hours, the best online site is Universalis.com. See the links below:

Also, Phyllis Tickle, someone I'd consider a "Progressive Christian," has
written a number of books on fixed-hour prayer, you can read her overview of the
topic here:

"But I call upon God,
and the Lord will save me.
Evening and morning and at noon
I utter my complaint and moan,
and he will hear my voice."
-- Psalm 55:16-17
