Answer:
The Catholic version of the "Our Father" remains straight out of scripture as:
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.
Amen
After Vatican II, in an attempt to better adapt the Mass to emerging ecumenical standards, the Our Father prayer had a verse inserted after it that is often attributed to Martin Luther, who wrote it as a footnote in his own Bible, but which is actually first seen in the Didache which was written at the advent of Christianity. It is commonly used by the Protestants. This line reads "For thine is the kingdom, the power and the glory, now and forever." This is only found in modern versions of the Catholic Mass as an ecumenical offering of the post-Vatican II liturgical commission though is not actually part of the "Our Father" nor is it added in the recitation of the "Our Father" when prayed outside of Mass, for instance, like in the Rosary.
