Reading the Catena Aurea with the day's Gospel recently, in the context of heresy, we encountered the wonderful word for weeds that grow and are sown among the wheat: tares (pronounced tears, like a tear in my shirt). Tares of the soul are those weedy thoughts that quickly got to seed, spreading their worldly temptations on the winds of our soulscape and sow themselves into our clay so we cannot distinguish them from our own thoughts.
