Seven virtues
The "Catechism of the Catholic Church" defines virtue as "a habitual and firm disposition to do the good." Traditionally, the seven Christian virtues or heavenly virtues combine the four classical cardinal virtues of prudence, justice, temperance and courage (or fortitude) with the three theological virtues of faith, hope and charity. These were adopted by the Church Fathers as the seven virtues.

"The thickness of your skin shall be seven spans" -- which is to say that you shall be proof against anger, offensive actions and criticism. [...] "Look and listen for the welfare of the whole people and have always in view not only the present but also the coming generations", even those whose faces are yet beneath the surface of the ground -- the unborn of the future Nation."Oren Lyons, Chief of the Onondaga Nation, writes: "We are looking ahead, as is one of the first mandates given us as chiefs, to make sure and to make every decision that we make relate to the welfare and well-being of the seventh generation to come. ... What about the seventh generation? Where are you taking them? What will they have?"
