On September 27th, 1540, the Society for Jesus received formal recognition from Pope Paul III. Loyola had been ordained as a priest in 1537 and he spent much time in Rome where he organised the work of the Jesuits. Loyola had become convinced that he could not do his work within an existing order, hence his determination to start his own.
He was a role model to many and inspired others to stay loyal to God. For example, Francis Xavier was one of the original followers of Loyola. In 1541, he was invited to go to the East Indies by John III of Portugal. He traveled extensively in great hardship but it is estimated that Xavier converted more than 700,000 people to the Catholic faith, just like the Society of Jesuits have.
