St. Ignatius of Loyola, born in 1491 in Spain, was a soldier who transformed into the founder of the Jesuit order in 1540, which continues to operate under the motto 'Ad Maiorem Dei Gloriam.' He experienced severe physical suffering due to multiple surgeries that did not fully heal his leg, yet this pain led to his spiritual conversion through reading religious texts and having a vision of Mary and Jesus. After a failed missionary journey to the Holy Land, he pursued formal education to enhance his ability to spread his message.
