Morituri non cognant
who are about to die, but just don't know it

Una salus victus nullam sperare salutem
The one hope of the doomed is not to hope for safety.

The one safety for the vanquished is to abandon hope of safety knowing there is no hope that can give one the courage to fight and win
-Virgil's Aeneid

And Sheperds we shall be-Boondock saints
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.
-Boondock Saints
