Humanists were people who wanted to return to ideas found in old Greek and Latin writing of Greece and Rome, written many centuries earlier. Christian Humanists also wanted to get back to these ideas, but they were mainly concerned with learning about the early Christian Church, before it had become involved with money-making and superstition. They wanted to read the books of the early Church, especially the gospels of Christ, in the original language of Greek, so that they would know exactly what the writings meant. The leader of the Christian Humanists was Desiderius Erasmus (1466-1536), who attacked superstitions in the Catholic Church in his writing.
