In the words of Jewish liturgical scholar Lawrence Hoffman, 'Jews do offer freely composed prayers... But overall, it is the fixed order and content of Jewish prayer that gives it its distinctiveness and that demands the personal commitment to prayer as a discipline.
But if roteness is a danger, it is also the way liturgy works. When you don't have to think all the time about what words you are going to say next, you are free to fully enter into the act of praying; you are free to participate in the life of God.
Sure, sometimes it is great when, in prayer, we can express to God just what we feel; but better still when, in the act of praying, our feelings change. Liturgy is not, in the end, open to our emotional whims. it re-points the person praying, taking him somewhere else.
Moses Luzzatto always said to be patient during the hard times, that they would have to endure and make sacrifices while they waited for better times to come. He urged Simone and the other Jewish boys not to provoke the Venetians, saying they should remain separate and focus on their work. He said their traditions were crucial to their identity, just as they were for their fathers before them.
