Jesus said to his disciples, ‘In your prayers do not babble as the pagans do, for they think that by using many words they will make themselves heard. Do not be like them; your Father knows what you need before you ask him. Matthew 6:7-15
Do we babble? I hope not. Why then the long prayers like the Office of Readings or the Mass? My answer: we do not use many words in order to be heard, but rather to hear more the word of God, straight from Scriptures or expounded for clearer understanding.
