It takes tremendous faith and enormous strength of character to make and accept such a selfless decision. I wish you could have seen (can't find a picture on the web) the image of her daughter, Gianna, assisting her father as he went up to receive the pope's blessing. St. Gianna's son is a priest; he concelebrated the mass with the Holy Father.
Not everyone is called to this level of spirituality. In the case of this family, it reflects their deep devotion and total commitment to life.
What are you saying? That some people are called to murder? That refraining from murdering your unborn child is "heroic"?
St. Gianna did nothing more than what was expected of her and of every Catholic mother facing the same situation.
