It is difficult to see how some Christians can criticize the
private prayer life of other Christians. One such criticism
centers on the element of repetition of the prayer, "Hail Mary."
But to even the casual reader of the word of God it must be
apparent that the writers of the Bible--and God Himself--used
the repetition of words and expressions in prayer.
The Bible uses repetition to indicate emphasis and the highest
degree of something.
"Holy, holy, holy is the Lord of Hosts!" they (the
Seraphim) cried one to another.
The Psalms are a good example of repetition in prayer.
Psalm 150 records a twelve-fold repetition in one psalm.
One wonders if the prayerful repetitions found in all prayer
services, especially "Halleluia" are modeled after the Psalms?
