The process of "saint making," more properly called the process for canonization, is normally long and complex. The candidate for sainthood must first be proposed to the local bishop. Once the bishop accepts and formally opens the "cause" for canonization, a thorough investigation into the person's life and work is begun. This entails an exhaustive study of the candidate's written works and, when possible, interviews with those who knew or worked with him. There is careful scrutiny of his life, virtues and weaknesses. The investigation aims at getting at the truth of the person's life and virtue. Only one who has lived the Christian life in an extraordinary manner, who has manifested "heroic virtue," can be seriously considered for canonization.
