"You need to keep yourself far away from three things. First, keep yourself from ever quarreling or being in strife with anybody. If you conduct yourself otherwise, you can say farewell to peace and charity....

Second, keep yourself from vainglory, or self-conceit, which is the vice that attacks devout people the most. Without our noticing it, this vice nudges us to want to stand out more than others and to want others to admire us. Even St. Paul warns his beloved Philippians about this 'Do nothing from selfishness or conceit' [Phlippians 2:3].... Self-abnegation that considers others better than yourself is the only remedy for this vice.

You need to guard against a third thing that is no less dangerous than self-conceit because it contains the hellish seed of division: Never put your welfare ahead of that of others, because it always and necessarily tends to break the beautiful bond of love, the bond that should always unite Christians. In St. Paul's words, love 'binds everything together in perfect harmony' [Colossians 3:14].  -St. Pio of Pietrelcina
