Rome has a deep Christian history that dates back centuries. Experts believe that the Christian religion was initially brought to Rome in the first century AD. However, it wasn’t as popular in ancient times as it is now. During this time, many people were persecuted for their beliefs. Those who practiced Christianity openly lost their rights, and some individuals lost their lives. Those who opposed Christianity destroyed ancient Christian texts and completely outlawed group worship. It wasn’t until Emperor Constantine issued the Edit of Milan in 313 that the persecution of Christians ended. Constantine granted them freedom to practice their religion. Shortly after, construction began on many churches and cathedrals to accommodate the Christian population.

The Archbasilica of Saint John Lateran is the Oldest Church in Rome

The Archbasilica of Saint John Lateran is short for Archbasilica Cathedral of the Most Holy Savior and of Saints John the Baptist and John the Evangelist in the Lateran. This is the official seat of the Pope, making it not only the head of all Roman churches but also the mother church of the whole world. It is the highest-ranking church in the world, even surpassing St. Peter’s Basilica.

Since this church was founded in the year 324, it is roughly 17 centuries old. Currently, it is the oldest standing church in the entire world. Originally, this building was a mansion belonging to the Laterani family. However, it was seized by the government when suspicions arose that members of the family were conspiring against the state. Many years later, Constantine, the first Christian Roman Emperor, took possession of the property. He later donated it to the Roman Church, and officials quickly began converting it into a beautiful basilica. Shortly thereafter, Pope Sylvester I performed a dedicated and it became the official residence of the papacy until 1308.

The Archbasilica of Saint John Lateran enjoyed many years of success and growth after its founding. However, a few centuries later, the Avignon Papacy began. This was a period of time between 1309 and 1376 during which seven popes resided in Avignon, France rather than Rome. It was during this time period that The Archbasilica of Saint John Lateran became somewhat neglected. Two fires destroyed sections of the building, and by the time the Avignon Papacy had come to a conclusion, it was in a state of disrepair. When the Pope returned to Rome, officials deemed The Archbasilica of Saint John Lateran unfit to be his residence. Shortly after, construction began on the Vatican, which has been the official papal residence ever since.

It wouldn’t be until Pope Sixtus V came into power that reconstruction of the church would begin. Instead of restoring the original building, he elected to rebuild an entirely new church. This is but one of his achievements, as he became known as the “Rebuilder of Rome.” Since this time period, The Archbasilica of Saint John Lateran has gone through countless restorations and additions in order to maintain its integrity and original beauty.
