Temperance

The Sunday Challenge = Seven heavenly virtues.
In the Catholic catechism, the seven Christian virtues or heavenly virtues refers to the union of two sets of virtues: the four cardinal virtues, from ancient Greek philosophy, are prudence, justice, temperance (meaning restriction or restraint), and courage (or fortitude); and the three theological virtues, from the letters of Saint Paul of Tarsus, are faith, hope, and charity (or love). These were adopted by the Church Fathers as the seven virtues. Do one, or all, or any, process or not.
