It was during this year of conversion that he began to write down material that later became his greatest work, the Spiritual Exercises.
He finally achieved his purpose of going to the Holy Land, but could not remain, as he planned, because of the hostility of the Turks. He spent the next 11 years in various European universities, studying with great difficulty, beginning almost as a child. Like many others, he fell victim twice to the suspicions of the time, and was twice jailed for brief periods.
In 1534, at the age of 43, he and six others (one of whom was St. Francis Xavier) vowed to live in poverty and chastity and to go to the Holy Land. If this became impossible, they vowed to offer themselves to the apostolic service of the pope. The latter became the only choice. Four years later Ignatius made the association permanent. The new Society of Jesus was approved by Paul III, and Ignatius was elected to serve as the first general.
When companions were sent on various missions by the pope, Ignatius remained in Rome, consolidating the new venture, but still finding time to found homes for orphans, catechumens and penitents. He founded the Roman College, intended to be the model of all other colleges of the Society.
Ignatius was a true mystic. He centered his spiritual life on the essential foundations of Christianitythe Trinity, Christ, the Eucharist. His spirituality is expressed in the Jesuit motto, ad majorem Dei gloriamfor the greater glory of God. In his concept, obedience was to be the prominent virtue, to assure the effectiveness and mobility of his men. All activity was to be guided by a true love of the Church and unconditional obedience to the Holy Father, for which reason all professed members took a fourth vow to go wherever the pope should send them for the salvation of souls.
