Saint Anselm

“ It ought not to be disputed that rational nature was made holy by God, in order to be happy in enjoying Him. For to this end is it rational, in order to discern justice and injustice, good and evil, and between the greater and the lesser good. ”

“ It is, therefore, established that rational nature was created for this end, viz., to love and choose the highest good supremely, for its own sake and nothing else; for if the highest good were chosen for any other reason, then something else and not itself would be the thing loved. But intelligent nature cannot fulfill this purpose without being holy. ”

“ But if it were not made holy for this end, that it might follow what it loves and chooses, then in vain was it made to love and choose holiness; and there can be no reason why it should be ever bound to follow holiness. ”
