Around 30 AD, the Holy Spirit came to the apostles and gave them the authority to share Jesus’ teachings. Known as Pentecost, this marked the start of the Christian Church and the spreading of the faith. The apostles acquired the ability to speak in different languages and were able to communicate with people from all over the world.

The Council of Jerusalem transformed the early Christian Church. Apostles like Peter, James, and Paul gathered to decide if non-Jewish converts to Christianity had to follow Jewish rules. They agreed in Acts that Gentiles didn’t need to follow these rules, allowing Christianity to extend beyond Jewish groups. The Council heard both sides and then made a considered decision.

Conversion of Constantine (312 AD)

In 312 AD, Constantine’s conversion changed the course of Christianity forever, from persecution to acceptance. Before the Battle of Milvian Bridge, he saw a cross in a vision and became a Christian. He then issued the Edict of Milan in 313 AD, giving Christians freedom to practice their faith in the Roman Empire.

Convened by Constantine, this council was an assembly of religious delegates arranged by Constantine I between May and August AD 325. The council’s decision stated that Jesus is “of one substance” with God the Father, establishing the belief in the Trinity and forming the basis of Christian teachings. The Trinity is one of the core concepts that Christians hold dear today.

The Council of Trent, held from 1545 to 1563 AD, was a direct response to the Protestant Reformation and created further divisions between the Roman Catholic Church and the Eastern Orthodox Church. Today, there’s a clear division between Catholicism and Orthodoxy for this very reason.
