LaComtesse, the Catholic version of the Lord's Prayer is:
"Our Father,
who art in heaven,
hallowed be thy name;
thy kingdom come;
thy will be done on earth as it is in heaven.
Give us this day our daily bread;
and forgive us our trespasses
as we forgive those who trespass against us;
and lead us not into temptation,
but deliver us from evil."
If said as a part of Mass however, the priest then says,
"Deliver us, Lord, from every evil, and grant us peace in our day. In your mercy keep us free from sin and protect us from all anxiety as we wait in joyful hope for the coming of our Savior, Jesus Christ."
The the priest and congregation say,
"For the kingdom, the power, and the glory are yours, now and forever."
Then the priest says,
"Lord Jesus Christ, you said to your apostles: I leave you peace, my peace I give you. Look not on our sins, but on the faith of your Church, and grant us the peace and unity of your kingdom where you live for ever and ever."
Then the priest and congregation say,
"Amen."
