Whether religion is the same as sanctity?

Objections

Objection 1 : It would seem that religion is not the same as sanctity. Religion is a special virtue, as stated above (Article [4]): whereas sanctity is a general virtue, because it makes us faithful, and fulfil our just obligations to God, according to Andronicus [*De Affectibus]. Therefore sanctity is not the same as religion.
Objection 2 : Further, sanctity seems to denote a kind of purity. For Dionysius says (Div. Nom. xii) that "sanctity is free from all uncleanness, and is perfect and altogether unspotted purity." Now purity would seem above all to pertain to temperance which repels bodily uncleanness. Since then religion belongs to justice, it would seem that sanctity is not the same as religion.
Objection 3 : Further, things that are opposite members of a division are not identified with one another. But in an enumeration given above (Question [80], ad 4) of the parts of justice, sanctity is reckoned as distinct from religion. Therefore sanctity is not the same as religion.
