What is a "Latter day Saint?"
So to answer this, I drew a picture: There are three main "types" of Christians. Catholics, Protestants, and Restorationists. Catholics believe that they are Christs original church. Protestants broke off from the Catholic Church and include Baptists, Presbyterians, Methodists, etc. Restorationists believe that Christs Church was restored to the earth after an apostasy or falling away.
