In the great 1943 movie Sahara, there is a line in the movie that mirrors who every Catholic is called to be.
In this movie Sergeant Joe Gunn (Humphrey Bogart) and his tank crew pick up five British soldiers, a Frenchman and a Sudanese man with an Italian prisoner crossing the Libyan Desert to rejoin their command after the fall of Tobruk. They and the Germans are greatly in need of water. The British Commander, Captain Jason Halliday (Richard Aherne) had one of the greatest lines in the film:
"We've only one purpose:
To save ourselves so that we can fight again."
This is what every Catholic is called to do. To stay confessed, with true repentance of heart for our sins, seeking God's mercy for ourselves so that we can be the conduit for that mercy for another.
The situation is bad, evil seems to not only surround us, but also outnumber us greatly. There must be a few souls whom at great peril to themselves will stand their ground and say, evil shall go no further!
Watch the movie, and join the fight.
