The heart of Christianity is in the doctrine of By Grace Through Faith for salvation. Mormonism and Catholicism teaches salvation by works. Many religions and cults and denominations and sects promote the ideas of works which is against the heart of Christianity.
The Roman Catholic Church emerged many years later. Catholicism split from Christianity. However, they lie and say that Christianity or Protestantism split from Catholicism. That is the tricky thing about history. There are many details that people can get lost in. So, it is important to look at the events of history in order.
First, you look at the Christ and his 12 disciples who became apostles. These men started having their own disciples and they started the early church 40 days after Jesus went into Heaven. The early church started around that time, as in around 30 AD or whenever it was. Some believe Jesus was around 33 years old when he was on the cross. He rose again the third day. He may have been born around 5 BC which means maybe he died around 28 AD.
Second, look at the early church which started around 30 AD. And the early church was not Catholicism. But if you ask Catholics, they will say they were part of the early church. That is a lie. The early church was the rise of Christianity and not the rise of Catholicism.
