To be fair, while it is not part of the Lord's Prayer to Catholics, but a distinct prayer (with very slightly different wording in English, mostly because the Greek goes through Latin to get to English), it has since 1970 been part of the Catholic Mass (Roman Rite) following the Embolism said by the priest immediately after the Lord's Prayer. So it is not exactly foreign or alien to the context of the Lord’s Prayer for Catholics, unless they fell through a 50+ year time portal.
