The followers of Christianity follow the holy book of the religion called the bible, which was actually split up into two books, the new testament and the old testament. The old testament came first and focused on how god had given his followers laws to live by if they wanted to be holy and be sent to heaven after death. The new testament shows how Jesus had fulfilled the laws of God. Christians follow theses laws in their place of worship, in churches. There are many churches around the world for Christians to come and pray at. Mainly a session of church is mainly held on Sundays, the break of the week, but others can pray on different days like a Friday night or a Saturday etc. A morning session of going to church consists of praying, holy songs, and usually a lesson that is spoken from one of the holy bibles. Although there are many churches around the world, there are significantly more important and older ones, like the catholic church, which the religious leader of Christianity is head of, the pope, pope Francis.
