But as I have said previously, repetition in prayer is not uncommon for any Christian.
Consider how repetitious so many extemporaneous prayers are. Consider also how many times we pray for the exact same thing: from world peace to healing for a particular illness.
The real problem is not so much the repetition but the intention: the idea that multiplying words will change God’s mind.
We cannot change God in se through our prayer. Rather, it is God who changes us through our prayer and who makes us his instruments of change through our prayer.
Extended and repeated prayer may have many effects on us. Sometimes it is like the old practice of writing repeated sentences in school, drumming important things into our brain.
The Rosary is particularly relevant in this regard, as it is built around meditation on the mysteries of our salvation in our Lord and Savior Jesus Christ.
...the wedding Feast at Cana...
Truly mysteries worthy of repeated meditation.
