1.) Exclusive loves are lower than non-exclusive ones. The limited diffusion of an interpersonal good arises from imperfection. Loves are to goods, and goods as such are diffusive. While marital and celibate loves are at least comparable, a love that excludes other persons is lower than one that doesn’t. This is Plato’s case for why eros must ultimately transcend itself in the love of greater common goods, ultimately to the good itself. In the Christian dispensation, love of God gives rise to a love that cannot be true to itself if it excludes any others, love of another in eros cannot be true to itself if it includes any others.
2.) Love of children makes it difficult to want to fly from the world. There will always be some tension between what we want to do in the world and our desire to leave it, but it would be heartless to unequivocally want to widow and orphan a family so as to join the Lord in the Eschaton. This element of detachment has a strong an unavoidable conflict with one’s role as spouse and provider.
3.) The sacramental is ordered to the non-sacramental. Sacraments are for those in via, even where they leave an indelible mark. This follows from their role as signs, as sensible mysteries, etc.
