alright, you win FULLMETALJACKET. I didn't think it would be that easy, cause most people have never heard of the movie, at least not that i've seen, and most people would look it up on the internet.
But, even on their official site, they say,
With which I quickly carry out thy command
Our feet may quickly carry out thy command
which is what they say in the movie
In nominee Patri Et fili, Spritus Sancti, Full Metal Jacket, you win.
And shepards we shall be
For thee, My Lord, for thee
Power hath descended forth from thy hand
That our feet may quickly carry out thy command
So we shall flow a river forth to thee
And teeming with souls shall it ever be
In nomini Patri, et Fili, Spiritus Sancti
