.In 1963, the Second Vatican Council decreed a revision of the liturgy (undertaken by the ICEL, International Commission on English in the Liturgy). In 1969, the doxology was added to the Catholic Mass, not as part of the "Our Father", but following shortly afterwards. In the Mass, the Lord's Prayer is spoken together, followed by the Priest praying:

"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."

and then the doxology ("For the kingdom, the power, and the glory are yours, now and forever") is prayed by the congregation

This section of the mass falls just before the sharing of the peace, where the priest wishes the congregation the peace of Christ with the words "The peace of the Lord be with you always" and all who are present share God's peace by shaking hands or embracing each other (depending on the customs of the church).
