The four classic cardinal virtues in Christianity are temperance, prudence, courage, and justice. Christianity derives the three theological virtues of faith, hope and love (charity) from 1 Corinthians. Together these make up the seven virtues.
Temperance is defined as moderation or voluntary self-restraint. It is typically described in terms of what an individual voluntarily refrains from doing. This includes restraint from retaliation in the form of non-violence and forgiveness, restraint from arrogance in the form of humility and modesty, restraint from excesses such as extravagant luxury or splurging now in the form of prudence, and restraint from excessive anger or craving for something in the form of calmness and self-control.
It is generally characterized as the control over excess, and expressed through characteristics such as chastity, modesty, humility, self-regulation, hospitality, decorum, abstinence, forgiveness and mercy; each of these involves restraining an excess of some impulse, such as sexual desire, vanity, or anger.
Temperance is a virtue akin to self-control. It is applied to all areas of life.
St. Thomas calls it a “disposition of the mind which binds the passions”.
Consider the major improvement in our current society if we learned to apply the lesson of temperance and generally subdue our passions.
