Louis Massignon was a Catholic scholar of Islam and a pioneer of Catholic-Muslim mutual understanding. He was an influential figure in the twentieth century with regard to the Catholic church's relationship with Islam. He focused increasingly on the work of Mahatma Gandhi, whom he considered a saint. He also played a role in Islam being accepted as an Abrahamic Faith among Catholics. Some scholars maintain that his research, esteem for Islam and Muslims, and cultivation of key students in Islamic studies largely prepared the way for the positive vision of Islam articulated in the Lumen gentium and the Nostra aetate at the Second Vatican Council. Although a Catholic himself, he tried to understand Islam from within and thus had a great influence on the way Islam was seen in the West; among other things, he paved the way for a greater openness inside the Catholic Church towards Islam as it was documented in the pastoral Vatican II declaration Nostra aetate.
