I read from The Routledge Reader in Christian-Muslim Relations https://www.routledge.com/The-Routled...

The profile picture features Thomas Aquinas (died 1274) who was an Italian philosopher, Catholic priest, and Doctor of the Church. An immensely influential philosopher and theologian he was the foremost proponent of natural theology and the father of Thomism. His influence on Western thought is considerable, and much of modern philosophy developed or opposed his ideas, particularly in the areas of ethics, natural law, metaphysics, and political theory. I admire his extraordinary intellect and theological brilliance though I do not agree with his Trinitarianism.

The points at issue and the arguments about them remain similar if not identical to those of Thomas’ day. This short tract, De rationibus fidei contra Saracenos, Graecos et Armenos ad Cantorem Antiochenum, was written by St. Thomas Aquinas at Orvieto, Italy, in 1264.
