B-branches.
Okay, so you've got Jesus Christ and his followers who, after his ascension, started to preach Christianity. But, the early Church had some problems. The Church didn't believe in religious freedom, they thought everyone had to be Christian! They even started KILLING people who weren't!
This period became known as the Reformation. Many people became part of the Protestant religion, which protested against the Church. Then people all over Europe began making new branches of Christianity. Some of these are Methodist, Ammonite, or Baptist. These branches are still Christian, but their beliefs differ.
There is however, a solution to unite these branches. It is called ecumenism. It means to work with other religions. There is a lot of historical wedges between these branches, but perhaps there is still hope for unity
