Did Jesus Really Warn Against Repetition in Prayer?

"In praying, do not babble like the pagans, who think that they
will be heard because of their many words." Matthew 6:7 (New

repetitive prayers? Does praying the rosary contradict the way
Jesus asked us to pray? Why is the rosary even designed that way?
Whether you pray the rosary everyday or have never prayed it
before, Fr. Mike has some insights from Jesus and his Church
regarding repetition in prayer that will change the way you look at
