Thomas Aquinas

“ To pay worship to God as Creator, as religion does, is more excellent than to pay worship to one's father in the flesh, as the piety that is a virtue does. But to pay worship to God as Father is yet more excellent than to pay worship to God as Creator and Lord. Wherefore religion is greater than the virtue of piety: while the gift of piety is greater than religion. ”

“ As by the virtue of piety man pays duty and worship not only to his father in the flesh, but also to all his kindred on account of their being related to his father so by the gift of piety he pays worship and duty not only to God, but also to all men on account of their relationship to God. ”

“ It seems that the second beatitude, "Blessed are the meek," does not correspond to the gift of piety. For piety is the gift corresponding to justice, to which rather belongs the fourth beatitude, "Blessed are they that hunger and thirst after justice," or the fifth beatitude, "Blessed are the merciful," since as stated above (A [1] , OBJ [3] ) , the works of mercy belong to piety. Therefore the second beatitude does not pertain to the gift of piety.
Objection 2: Further, the gift of piety is directed by the gift of knowledge, which is united to it in the enumeration of the gifts (Is. 11) . ”
