The Rosary is indeed a repetition of prayers ... but NOT vain repetition ... or useless repetition.

In this passage of St. Matthew, our Lord is condemning the Pharisees who "loved to stand in the corners of the streets that they might be seen by men." They talked to God only to be seen by men.

Our Lord never condemned repetition in prayer. He Himself repeated the self-same prayer three times in the Garden of Gethsemani. (Matt. 26:39, 42, 44). The blind man repeated his prayer and was cured by Christ. (Matt. 20:31). We are told that the angels of God in heaven never cease repeating, night and day, the canticle: "Holy, Holy, Holy, Lord God Almighty." Apoc. 4:8.

Repeated prayers are not necessarily mechanical or unnecessary. The girl who is in love does not rebuke her boy friend for repeating the statement that he loves her.

In the Rosary, Catholics repeat the Scriptural prayers: the Lord's Prayer (Matt. 6) and the Angelic Salutation, or "Hail Mary," found in Luke 1:28.
