text: Is Bannon a cultural Catholic or one of conviction?
  If he receives parish envelopes, the latter; if not, the former.
  One of the 5 precepts of RCC is to support the church by supporting the pastor.
  Is SB registered in any parish?
  If registered, envelopes are mailed.
  Is there any record of his support of his pastor?
  I'd vote he's a cultural Catholic.
  Like Bridgit Bardoe when asked what religion she belonged to, respond, "Catholic, What else is there in France?"  Cultural.
