Íñigo de Loyola came to be a figure with a new historical significance in that same century and with the name of Ignacio de Loyola, Master Ignacio, the first Superior General of the Society of Jesus, author of Autobiografía, Ejercicios Espirituales, Diario Espiritual and Constituciones. He was the owner of his own destiny when he changed his name himself. This change was done through an equally refined as rapid transforming process of personal and collective self-definition in which several people participated, specially Jesuits, debugging his image. His written work was identified with his person. Thanks to his vital experience, Ignacio learned how to lay bridges in the dialectic combats of the two extremes that could be found in all areas, theologic (grace-liberty), dogmatic (science-bible), political (king-community), anthropologic (soul-body), spiritual (contemplation-action), ecclesiastic discipline (mental prayer-vocal prayer), scientific (science-experience), etc., or like he used to say, between Marta and Maria. It was, in a way, about still being enlightened and erasmist, at the same time as roman and hierarchic. He had the wisdom to combine both things, to make a religious project possible using policy, and to pose a political option making use of the religious life. Once dead, some understood, probably Ribadeneira better than no one else, what Ignacio always said: "The Society of Jesus was not mainly founded over Ignacio, but more over Jesus Christ, who had risen to this his servant to build and raise this work from his hands, and he his omnipotent to give us other and others, who although are not Ignatios, they will be whatever we need". In this conference I will focus on the analysis of his texts and the Society of Jesus since its foundation in 1540 till the death of Ignacio in 1556.
