““While paying attention to the messages in its public spaces, Christianity also wisely recognizes the extent to which our concepts of good and bad are shaped by the people we spend time with. It knows that we are dangerously permeable with regard to our social circle, all too apt to internalize and mimic others’ attitudes and behaviour. Simultaneously, it accepts that the particular company we keep is largely a result of haphazard forces, a peculiar cast of characters drawn from our childhood, schooling, community and work. Among the few hundred people we regularly encounter, not very many are likely to be the sorts of exceptional individuals who exhaust our imagination with their good qualities, who strengthen our soul and whose voices we want consciously to adopt to bolster our best impulses.””
