Early Life

Known as Sixtus from birth, Sixtus III also used the name Xystus from an early age. He was born sometime in 390 in Rome, Italy and spent his entire life in the Holy Roman Empire. Sixtus worked as bishop for the Church for many years before becoming the pope. He became a prominent member of the Roman clergy and developed a relationship with Augustine of Hippo who would later become a saint.

 

Papacy of Pope Sixtus III

Sixtus III became pope on July 31, 432 and consecrated in Rome. One of his first actions was to end the feuding between two major leaders at the time: John of Antioch and Cyril of Alexandria. The two men would finally reconcile one year later. He also spoke about the leadership of Illyria, which was a region of the Balkan Peninsula. Sixtus III believed that the pope should lead the people of this region and that he had more rights than others did. Those actions put him in direct opposition with the Proclus of Constantinople. The emperor of this region believed that he should have more control than the pope.

 

Architecture Boom

As the pope, Sixtus III became known for the architecture he helped create in and around Rome. Work finished on the Basilica of Santa Sabina during his reign and was dedicated to the pope. This historic church still stands today on Aventine Hill. He also helped build the Basilica di Santa Maria Maggiore, which he called the Liberian Basilica. Sixtus III dedicated this building to the Virgin Mary or the Mother of Christ. In making this dedication, the pope showed that he agreed with the Council of Ephesus. This council met to discuss whether the Church and its followers should consider Mary as the Mother of Jesus. Sixtus III’s dedication to the building showed that he believed she was the mother of Jesus. The pope also added work to a church in St. Lawrence Outside the Walls, which led to the building becoming a basilica.

 

Later Years

Though Sixtus III is a saint in the Catholic Church, he was not a martyr like the popes who came before him were. He spent much of his rein working on local churches and improving the buildings in Rome. The Congregation for the Causes of Saints did a preliminary investigation and determined that he deserved sainthood. Sixtus III ascended to the position in his early 40s and was just 50 when he passed away from natural causes. Eight of the letters that he wrote during his papacy still exist, including some that he wrote to Augustine of Hippo. At least three of the letters attributed to him such as On Chastity and On False Teachers are forgeries written at a later date.
