I have taught this constantly using words from holy Scripture. The world is not evil, because it has come from God's hands, because it is His creation, because 'Yahweh looked upon it and saw that it was good' (cf Gen 1:7 ff). We ourselves, mankind, make it evil and ugly with our sins and infidelities. Have no doubt ...
The world awaits us. Yes, we love the world passionately because God has taught us to: Sic Deus dilexit mundum ... - God so loved the world. And we love it because it is there that we fight our battles in a most beautiful war of charity, so that everyone may find the peace that Christ has come to establish. (Furrow, 290)
"It is in the midst of the most material things of the earth that we must sanctify ourselves, serving God and all mankind.”
