The importance of the new religious orders that spread new ideas and customs of the 12th and 13th centuries is as significant today as it was at the dawn of the history of Christianity. In order for Christians to look beyond the realm of the great and informative of the early teachings there were three philosophers and theologians of that time. To discuss these three men of God, their ideas and knowledge were a great insight into a new and fresh tradition among their followers and congregations. These new orders established by Saint Francis and Saint Dominic and their emulators maintained and propagated faith in the souls of men and social intuitions throughout the empire. These acute directions of the work of redemption of Christian prisoners were also produced in the “Summa Theologica” of Saint Thomas Aquinas. He was the prince of Christian doctors and moralists, whom the faith considers as the most faithful interpreter of Catholic traditions and inspired by Aristotle. St. Dominic and the Dominicans, St. Frances of Assisi and the Franciscans, and St. Thomas Aquinas and Thomism all played significant roles in early Christianity. Saint Dominic was born in Calaruga, Ancient Castile, Spain, the son of Felix Guzman and Blessed Joan of Aza. He studied at the University of Palencia, where he was ordained a priest. Saint Dominic was a man of God who continually praised him. He abstained from meat and observed prescribed fasts and periods of silence. He often did not wear sandals and wore minimal clothing, as Domenico was the first to follow the lifestyle he gave to others. He never had a bed, usually sleeping on the side of the road. Saint Dominic founded a women's institute in Prouille, in the Albigensian territory... in the center of the sheet... a decisive moment in the theology of the medieval West. These three men of God, Saint Dominic Guzman of the Dominican Order, Saint Francis of Assisi and Saint Thomas Aquinas had and have a very significant value in the early years of Christianity. Without these great men and their ideas of spreading the word and living without worldly possessions, it is very likely that Christianity and Catholicism would be different than they are today. It's easy to say that these three men lead their lives by example. They remained true to their moral beliefs and lived very humbly. It was a different time than when these saints roamed the countryside, preached and prayed. It is now of fundamental importance for the Christian faith to live and study this theology. As Christians from the 13th century to the present day, Christianity is the hope of the world.
