Growing up, I learned the version of the Lord’s Prayer that you see to the right. When I joined the Catholic Church in 1985, I first learned the Hail Mary and many other prayers based on the traditional language.
Thy kingdom come, Thy will be done. Blessed art thou among women, and blessed is the fruit of thy womb, Jesus.
I guess I just assumed that this was my “church language”, kind of like dressing up for Mass.
It seemed respectful and appropriate. Formal.
