The Library of Congress Classification system includes numbers for a long list of both Christian sins and virtues -- both of which are listed alphabetically.
In the latter, along with the virtues one might quickly guess, such as courage (BV4647.C75), kindness (BV4647.K5), patience (BV4647.P3) and sympathy (BV4647.S9), there are less common terms such as concord (BV4647.C6), filial piety (BV4647.F45) and magnanimity (BV4647.M2).
Amongst the sins, there are idolatry (BV4627.I34), jealousy (BV4627.J43) and lust (BV4627.L8) along with acedia (BV4627.S65), licentiousness (BV4627.L5) and partisanship (BV4627.P3).
Most interesting to me was the final listing in the virtues category: wrath. So, between the road-ragers and those that sit back and take it, the roads are full of the virtuous in the eyes of the Christian God and the Library of Congress... yet full of the sinful at the same time:
Virtues: acquiescence (BV4647.A25) and wrath (BV4647.W7).
Sins: anger/revenge (BV4627.A5/BV4627.R4) and ... well, "blessed are the meek (BV4647.M3), for they shall inherit the earth" (Matthew 5:5).
So I guess the lesson here is to let the road-ragers blow on ahead. Your mom was right. (And you're less likely to get shot.)
