The Boondock Saints Prayer
The Boondock Saints prayer is also known as "The Family Prayer". It is an oath to God. Basically, the boondock saints are saying that they will do all they can to help rid the world of evil, and help the weak.
And Shepherds we shall be
For thee, my Lord, for thee.
Power hath descended forth from Thy hand
Our feet may swiftly carry out Thy commands.
So we shall flow a river forth to Thee
And teeming with souls shall it ever be.
In Nomeni Patri Et Fili Spiritus Sancti.
The final part of this prayer from the Boondock Saints is in Latin. It's translation is, more or less, "In the name of the father, of the son, and the Holy Spirit".
The prayer was written by the director, so the meaning is up to interpretation. The only part of the prayer that appears in the bible is the last sentence.
The Boondock Saints has become a bit of a cult phenomenon. Many people have bought the movie since it's release, and posters of this prayer hang on many dorm room walls. Dudes tend to think it's pretty bad ass.
Also, many people have gotten the prayer as a tattoo.
