In Matthew 28:19, before Christ ascended to heaven, He instructed all his apostles to teach all nations, baptizing them in the Name of the Father, and of the Son and of the Holy Spirit. And so, after the day of Pentecost (i.e. the birth of the Catholic Church) when all the apostles received the Holy Spirit, they began to travel on different cities and countries. Some of them had went far from Jerusalem, such as St. Thomas who arrived in India, establishing Christianity to a Hindu majority nation. Apostle James the Greater also went to Spain where he established Christianity to a country which was responsible for the Christianization of many Spanish colonies (e.g. Mexico, Philippines, Puerto Rico, and many Latin American Countries) in the world. St. Paul had also went to Spain in one of his journeys (Rom.15:24).

All of the 12 Apostles (except St. John) have died in martyrdom. Apostle John died on natural death after he wrote the Book of Revelations. The remains of all Apostles (except Judas Iscariot, perhaps protestant kept his remains) were all kept and venerated by the early Christians. In the Old Testament, the Israelites had kept and carried with them the bones of Joseph (read Exodus 13:19). The only Church who preserved the remains of the Apostles from early Christianity until now is the Catholic Church. Details on how all apostles died and where their remains are kept are the following:

(Paul was not part of the original 12 apostles who were personally selected by Christ. He was a convert to Christianity and is considered as the Apostle to the Gentiles)

Please note that all of the locations where the remains of Apostles are being kept are inside “Catholic” churches custody. There is none of the remains of the apostles that is buried in any protestant church. It only proved that from the very beginning of Christianity, it was really the Catholic Church who are the original christians who followed the teachings of Christ and his apostles.
