Quote from the article:  "What I would like is a clarification about martyrdom in odium fidei, whether it can occur either for having confessed the Creed or for having done the works which Jesus commands with regard to one's neighbor," Francis said then.

Why not either/both?  Or is that what Pope Francis is suggesting?  Faith is action.  Faith explored in one's mind and not experienced in the heart is an interesting mental exercise - such as working the Sunday crossword puzzle.  Fr. Rother returned to Guatemala knowing there was a threat to his life - and he was killed.  

While on this subject, is there some problem in recognizing the 2 nuns and 2female church workers who were raped and killed in El Salvador in 1980?  Is there some different criteria for priest versus nun versus lay, male versus female?  I get it that it has been hard to get the Church to recognize modern day martyrs, especially from the Americas.  And I think Fr. Rother needs to be recognized - but so do the women!
