Rituals are actions we do to help us pay attention to important things in life, to express outwardly what we believe to be important. To celebrate something, to show the meaning we place upon a thing which is not readily visible. Rituals also are extremely important bonding tools.
And when you pray, do not be like the hypocrites, for they love to pray standing in the synagogues and on the street corners to be seen by men. I tell you the truth, they have received their reward in full.
But when you pray, go into your room, close the door and pray to your Father, who is unseen. Then your Father, who sees what is done in secret, will reward you.
And when you pray, do not keep on babbling like pagans, for they think they will be heard because of their many words.
Do not be like them, for your Father knows what you need before you ask him (Mt 6:5-8)
The Church doesn't give you faith, MarMema. The Liturgy is what they call "Sunday Worship" -- a ritual Mystery Supper for those who already believe and who come to adore and worship God, not to become religious.
Faith is between you and God. In the privacy of your soul. That is the most important thing in life.
