Virtue: refers to faith, hope, and love (theological virtues), as well as prudence, justice, fortitude, and temperance (cardinal virtues). Virtue is an overflow of grace; a response to grace and a participation in the life of grace. The three theological virtues--faith, hope, and love--are infused into the soul upon baptism and are considered to be a unique participation in the life of the Trinity. The theological virtues are pure gift, infused within the soul upon baptism. The four cardinal virtues--prudence, justice, fortitude, and temperance--are habits established through practice. While wholly insufficient for salvation when left to themselves, the four cardinal virtues are signs of a mature Christian life.
