In spiritual terminology, piety is a virtue. While different people may understand its meaning differently, it is generally used to refer either to religious devotion or to spirituality, or often, a combination of both. A common element in most conceptions of piety is humility.
It can refer to a way to win the favor or forgiveness of one's God, or gods, (i.e., to propitiate Him/them). According to some, this type of piety does not necessarily require the spiritual piety, while others refrain from distinguishing the two.
It is also used by others to refer only to external signs that result from the spiritual aspect of piety. That is, according to some, if one is "truly" pious (in the spiritual sense), the natural and inevitable result of it will be religious piety. By this definition, then, piety can be either genuine, in that it springs from spiritual piety, or false, in that it is an attempt to exhibit the signs of piety for their own sake, or for some other reason, (such as propitiation or public esteem).
In Catholicism and Anglicanism, piety is one of the Seven gifts of the Holy Spirit.
