“‘Our Father in heaven,
hallowed be your name,
¹⁰ your kingdom come,
your will be done,
    on earth as it is in heaven.
¹¹ Give us today our daily bread.
¹² And forgive us our debts,
    as we also have forgiven our debtors.
¹³ And lead us not into temptation,
    but deliver us from the evil one.

It is also in Luke  11:1-4:
11 One day Jesus was praying in a certain place. When he finished, one of his disciples said to him, “Lord, teach us to pray, just as John taught his disciples.”

² He said to them, “When you pray, say:

“‘Father,
hallowed be your name,
your kingdom come.
³ Give us each day our daily bread.
⁴ Forgive us our sins,
    for we also forgive everyone who sins against us.
And lead us not into temptation."

These words were spoken by a man that Jesus found begging for his servant to heal.You can find this in Matthew 8.

How does this prayer sustain the catholic church?
Well,I browsed the web for this prayer  and many articles are of people saying how true and powerful is the meaning of the prayer and how moved they felt by it.These words show the power of jesus and that people get a powerful grip on faith
