Who helped set up a Christian church in Rome after the death of Jesus?

Answer 1

There were many people who might be considered leaders who helped set up the early Christian church. Jesus was the person who actually founded the church, but describing him as having "helped set it up" seems an inaccurate description. In my opinion, a good candidate for that role would be Paul, who not only made great strides in setting out the theology of the early church, but also was the first official missionary to the Gentiles and helped to spread Christianity as far as Rome, among other places.

Other answers:

One of the earliest recorded champions of Christianity in the Roman Empire was the Emperor Constantine, who changed the national religion of all of Rome to Christianity.

You also need to research the first popes to get a full background on the development of the church and it's hierarchy.

Henry the 8th helped set up the Anglican Church (also known as the Church of England).

From a Bible standpoint:

The church began in Jerusalem around 30 AD. Acts of the Apostles is a history of the birth and development of the "early" (true) church, and contains the answer to your question.

Answer 2

The disciples of Christ helped spread Christianity in the beginning after Christ descended back into Heaven. The Holy Spirit was sent down to bring conviction and comfort to people. Paul also helped spread Christianity to the Gentiles, non-Jewish people. Each one was called by God in unique ways.

Answer 3

St Peter and the apostales John, James & Paul

Answer 4

The earliest and best-known example would be Paul, who specialized in missionary work to the non-Jews and set up churches in every town where he ministered.
