In the first place it should be noted that the title had been in common use long before, and was employed by the Brothers of the Common Life, to designate any of their pious publications. Even Ludolph of Saxony speaks of the "Studia spiritualis exercitii." Secondly, the "Ejercitatorio" is rigid in its divisions of three weeks of seven days each, whereas St. Ignatius takes the weeks in a metaphorical sense, and lengthens or shortens them at pleasure. Thirdly, the object of the Benedictine manual is to lead the exercitant through the purgative and illuminative life up to the unitive; whereas St. Ignatius aims chiefly at the election of that state of life which is most pleasing to God, or at least at the correction or betterment of the one in which we happen to be. Finally, the "Ejercitatorio" does not even mention the foundation, the Kingdom, the particular examen, the Two Standards, the election, the discernment of spirits, the rules for orthodox thinking, the regulation of diet, the three degrees of humility, the three classes or the three methods of prayer. Only a few of the Benedictine counsels have been adopted, as in Annotations 2, 4, 13, 18, 19 and so. Some of thoughts, indeed, are similar in the first week; but the three succeeding weeks of St. Ignatius are entirely his own. In any case, the "Ejercitatorio" itself is nothing else than a compilation from Ludolph, Gerson, Cassian, Saint Bernard, Saint Bonaventure and contemporary writers. (Debuchy, article "Spiritual Exercises of Saint Ignatius" in the "Catholic Encyclopedia," XIV, 226.) It would be much easier to find a source of the "Exercises" in "The Great Life of Christ" by Ludolph of Saxony, which as has been said, was one of the books read by Ignatius in his convalescence. It is not really a life but a series of meditations, and in it we find a number of things which are supposed to be peculiar to the Exercises of St. Ignatius, for instance, the composition of place, the application of the senses and the colloquies. On the other hand there is nothing of the "first week" in it, such as the end of man, the use of creatures, sin, hell, death, judgment, etc., besides many other things which are employed as "Exercises" in the book of Ignatius.
