Did Christianity Start In Rome

Christianity is one of the largest religions on the planet and has had a major influence on the trajectory of human history. Modern Christianity has its roots in Rome, according to some theologians, but debate continues over exactly how early Roman society embraced the religion.

While it had initially been a small, persecuted minority religion, within two centuries of its first appearance in the Roman Empire in 339 AD, Christianity had become a major power within the state. This was possible due to a number of factors, from the development of an official structure of the faith to the implementation of laws that favoured the new religion.

In 313 AD, Roman Emperor Constantine issued the Edict of Milan, which made Christianity a legal religion in the Roman Empire. Increasingly positive attitudes towards Christianity by Rome’s rulers, such as Emperor Theodosius in 380 AD, further encouraged Christianisation and the religion soon became a major source of spiritual comfort, moral guidance and social status for millions of people.

Around 380 AD, Emperor Theodosius became the first Christian Emperor of Rome and granted the church extensive legal rights and privileges. This made Christianisation a much easier process, as church-run activities such as missionary work and charitable activities spread the faith quickly throughout the empire.

Many Roman leaders had an vested interest in Christianity for two main reasons. Firstly, it provided a powerful ideological tool for legitimising their rule, with the dogma of faith providing a moral compass for civil and state law, and secondly, it helped create social cohesion and stability by providing unity of belief. The Christian faith was thus embraced and supported by many Roman rulers, and over time it supplanted most other religious beliefs.

The role of the Roman Catholic Church in the history of Christianity is undeniable – it underwent a period of reform and reorganisation from the 4th century onwards and is regarded by many as responsible for the mainstream expression of Christianity that we know today. It also enshrined the authority of the Roman Church as the official representative of the faith and popularised many ideas, rituals, customs and traditions that are still practised.

In addition to the influence of Rome, the spread of the faith was also greatly assisted by the success of missionary activity from North Africa that promoted a ‘Latin’ version of Christianity. This had a direct impact on the faith of the Roman Empire, established it as the ‘mother church’ of Western Christianity, and laid the groundwork for the Christianisation of Europe.

The Impact of Constantine

The Edict of Milan of 313 CE, issued by the Roman Emperor Constantine, is widely considered to be a decisive moment in the history of Christianity. By allowing all religions, including Christianity, to be practiced freely, Constantine effectively granted Christianity the same status as the other major faiths of the era. This edict was ultimately a major factor in the eventual spread of Christianity throughout Europe.

Constantine was also a major influence in terms of the development of the Christian faith itself. Through his patronage of church leaders, he helped set the stage for the formulation of Christian doctrine and ritual. In addition, his involvement in the Council of Nicaea in 325 CE was critical in shaping the early Church’s beliefs. The product of this council, the Nicene Creed, is still in use today.

Not only that, but Constantine himself was a major influence on the development of Christianity. He was the first Roman Emperor to convert to the faith, and his example and patronage of the Church played a significant role in influencing other Roman elites to join him. He was also an important figure in the establishment of Christian practices and traditions, and was responsible for the founding of many churches and monasteries.

The Role of Rome

Rome was key to the spread of Christianity, and its influence can be seen throughout the history of the faith. From the conversion of Constantine to the development of Church doctrine, Rome was the epicentre of early Christian activity. From its earliest days, Christianity was intertwined with Roman culture, with the first Christians being traditionally identified as Roman citizens.

Rome also had a major impact on the development of the early Church. The Roman legal system provided a framework for the codification of Church laws, while the city’s urban infrastructure enabled the rapid spread of Christianity via missionary activity and the establishment of Christian churches. Rome was also the birthplace of many early Christian theologians and saints, who helped shape the faith and spread the Gospel.

The Catholic Church itself is rooted in the history of Rome, and is the largest and oldest Christian Church in the world. In addition to its influence on liturgy and doctrine, the Church has also been a major force in the development of Western art and culture, from the Renaissance onwards. This influence can still be seen today in the architecture and art of many European cities.

The Spread of Christianity

Once established in Rome, Christianity quickly spread throughout the Roman Empire, thanks to Roman systems of government and taxation, as well as well-organised Christian missionary activity. The spread of the faith was also assisted by Emperor Constantine’s legal reforms, which effectively made Christian legislation the law of the land. Christianity then spread further afield, as it was adopted by non-Roman cultures in Europe, Northern Africa, and the Middle East.

Christianity has likewise had a major impact on the development of world societies. In addition to its religious impact, it has also helped to shape legal systems, political structures and cultural norms. It has also been a major source of art and literature, as well as music and architecture. Simply put, Christianity has left an indelible mark on the history of the world.

Moreover, the Church provided social and moral guidance to its adherents in a world that was rapidly changing in terms of political and economic systems. Christianity was a major source of comfort for many people during this period, and its influence can still be seen in the values, customs and traditions of many modern societies.


Christianity is one of the most influential faiths in human history, and its origins in Rome are undeniable. From Constantine’s conversion to the Church’s position of authority in the Roman Empire, Christianity has developed and changed significantly from its early days in Rome. The role of Rome cannot be overstated when it comes to the spread of Christianity throughout Europe, the Middle East and beyond.

The influence of Christianity on the world has been immense, both in terms of its religious teachings and its influence on culture and art. Historians and theologians are unanimous in their agreement on the importance of Rome to Christianity and its future development and expansion. The Church’s strong ties to Rome are still evident today, and will no doubt remain so for many more centuries to come.
