“The saints are humanity’s great benefactors.” Pope Benedict XVI in Holy Women.
Our greatest benefactors are not the Bill Gates or Warren Buffets of the world. They give away money, which can be used by the devil to corrupt the recipients. The money can do a lot of good, of course, but so can having people speaking the same language and constructing great buildings.
Saints are the true benefactors of humanity. They are created by the grace of God with the cooperation from the saints themselves. Their work is their life itself, and God protects that work so their lives continue to inspire more people to become saints themselves.
