By Peter Kreeft, Catholic Education Resource Center - Why does the Church include All Saints' Day (Nov. 1) in her calendar of solemn feasts? Why does the Apostles' Creed include "the communion of saints" as one of the 12 essential articles of our faith? Because, as Charles Peguy put it, "life holds only one tragedy, ultimately: not to have been a saint.".. Saints are not freaks or exceptions. They are the standard operating model for human beings.
