At least, in the case of my family, our middle names are usually after the patron saints we're given upon being baptized. Amazingly enough, they seem rather accurate throughout the family in regards to the saint assigned, and the personalities of those with them.
Gotta say, I like having a badass archangel as my guardian angel/patron saint. For some odd reason, having patron saints (like the case mentioned earlier) feels like owning a zanpaktou from Bleach. If only I can invoke his spirit as a tangible weapon; but according to the Bible (in regards to his power and such), that could destroy the world.
Amazingly enough, at least from what I recall by experience, the patron saints are helpful to some degree. I mean, I can just list off how many incidents I probably wouldn'tve survived, resolved, or avoided; had it not been for asking for the assistance of St. Michael (using his very own prayer). So to put it, I owe my life hundreds times over had it not been for his assistance when I absolutely needed him most. Then again, having unwavering faith in these regards generally help alot.
Of course, sometimes, I actually have to question the logic behind some of the rescues or happenings; but after applying enough fridge logic, there's your miracle, and the disaster that smacks later once I realize (usually after I realize).
Sometimes, life tends to suck at times, but remember, it can always suck far worse. That's where these guys usually step in to help.
