The Bible tells us to avoid repetitious prayer. Isn’t the rosary a repetitious prayer?
In the Sermon on the Mount, Jesus says: “In praying, do not babble like the pagans, who think that they will be heard because of their many words” (Mt 6:7). My prayer or yours does not create an obligation that God must fulfill. That is the pagan attitude that Jesus rejected. Genuine prayer is all in the intention, not in the externals. The rosary has been a form of genuine prayer for many people over the centuries.
