114. Panta pisteúei. Love believes all things. Here “belief” is not to be taken in its strict theological meaning, but more in the sense of what we mean by “trust”. This goes beyond simply presuming that the other is not lying or cheating. Such basic trust recognizes God’s light shining beyond the darkness, like an ember glowing beneath the ash.
It’s also not blind faith that the beloved can do anything. Pope Francis sees a connection between trust in another person and having sight of the Lord through our relationships.
