The First Day
The first day of the retreat is mainly devoted to what St. Ignatius calls “The Principle and Foundation.”
Christ bids us act like “a wise man that built his house upon a rock,—and it fell not because it was founded on a rock” (St. Matth. vii, 24). The truth now considered is the rock on which the whole structure of our spirituality is to be built. Bartoli, in his life of St. Ignatius, narrates that a learned Doctor of the University of Paris, Martin Olave, used to say that one single hour spent in meditating on this foundation had taught him more than long years of theological studies. Such too has been the experience of many others. Father Everard Mercurian spoke of this foundation as alone sufficient to effect the most astonishing changes in a soul, by uprooting all its earthly affections and directing its desires to God alone.
