But idolaters are so called because they offer to their idols things belonging to men, and this not as outward signs which may excite in them spiritual affections, but as being acceptable by those idols for their own sake. And especially because they offered them empty and vile things. * * * * * _S. Augustine:_ When men pray, they, as becomes suppliants, make use of their bodily members, for they bend the knee, they stretch forth their hands, they even prostrate on the ground and perform other visible acts. Yet all the while their invisible will and their heart's intention are known to God. He needs not these signs for the human soul to be laid bare before Him. But man by so doing stirs himself up to pray and groan with greater humility and fervour. I know not how it is that whereas such bodily movements can only be produced by reason of some preceding act on the part of the soul, yet when they are thus visibly performed the interior invisible movement which gave them birth is thereby itself increased, and the heart's affections--which must have preceded, else such acts would not have been performed--are thereby themselves increased. Yet none the less, if a man be in some sort hindered so that he is not at liberty to make use of such external acts, the interior man does not therefore cease to pray; in the secret chamber of his heart, where lies compunction, he lies prostrate before the eyes of God (_Of Care for the Dead_, v.). VIII Is Religion the Same as Sanctity? In S. Luke's Gospel[71] we read: _Let us serve Him in holiness and justice._ But to serve God comes under religion. Hence religion is the same as sanctity. The word "sanctity" seems to imply two things. First, it seems to imply _cleanness_; and this is in accordance with the Greek word for it, for in Greek it is _hagios_,[72] as though meaning "without earth." Secondly, it implies _stability_, and thus among the ancients those things were termed _sancta_ which were so hedged about with laws that they were safe from violation; similarly a thing is said to be _sancitum_ because established by law. And even according to the Latins the word _sanctus_ may mean "cleanness," as derived from _sanguine tinctus_, for of old those who were to be purified were sprinkled with the blood of a victim, as says S. Isidore in his _Etymologies_.[73]
