Wait, is this line:
...not supposed to be in the Catholic version? Because I distinctly remember it from the masses I attended in my youth.
I think the official Catholic position (wish this was AAD so I could tag TJ) is that if you want to pray it with the last line personally that's fine, but it's not appropriate for liturgical use. I'd guess that the difference could be a language issue but all Catholic bibles are translated from some master version in Latin, which presumably wouldn't have that last line either in it. So...maybe some French diocese had a weird policy?
Catholics always pray the last line at Mass. It would be inappropriate not to say it during the liturgy. It's just not thought of as part of the Our Father because in between the Our Father and the doxology the priest prays:
"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."
This means that the doxology is always said in the Mass, but pretty much never outside of it.
