Gregory of Nazianzus

It happens with most people that they give indeed, but they do not do so freely and readily, which is a greater and more perfect thing than the mere act of offering itself. It is far better to be generous to the unworthy for the sake of the worthy than to deprive the worthy out of fear of the unworthy. This seems to have a bearing on our duty of casting bread upon the waters, not that it may be swept away or perish in the eyes of the just examiner, but that it may come to that place where all our goods will be stored up. And [it will] be there to meet us in due time, even though we may think otherwise.
