When Man creates things that are disordered and ugly, those things are not a reflection of Man but rather of Man’s disorder, Man’s brokenness. But in God there is no disorder, and therefore it would be repugnant to God to create that which is not beautiful, for the creation reflects the creator just as the art reflects the artist. And in this case, the creator is not just beautiful but is beauty itself.
All of creation and everything in creation is a reflection of God in some way, some aspects of God. On Trinity Sunday, we consider one part of God’s creation which reflects in a particular way that God is a Trinity, and then we will see some practical consequences that that ought to have for us. That particular aspect of God’s creation that we are talking about is marriage.
