Christianity and Islam are two of the most significant religions since their creation. Islam means "submission" in Arabic, and a Muslim is one who submits to the will of God (Islam page 223). Christians were called so because of Jesus' title Christos, which is Greek for Messiah (Christianity page 198). Both religions are very similar with only some of the beliefs and teachings being different. They also give separate messages to outsiders as to what their religions stand for. Both religions are monotheistic with a holy text and they both strive to conquer evil. Islam has a set of rules (5 Pillars of Islam) set forth to reach enlightenment while Christians basically just sin, repent, and then are forgiven for their sins. Christianity is a much easier religion to belong to because it is a lot more lenient to what you can and cannot do as well as when and where you can do it. Islam is also more closed doors because the do not really send out missionaries looking for people to convert to Islam.
For Christianity, Jesus of Nazareth was the Messiah (the anointed one) - God's deliverer, whose coming the prophets had foretold (Christianity page 198). Jesus taught the good Word of the Lord, as was his duty as the Son of God. He is also said to have performed miracles such as curing leprosy and blindness as well walking on water. Roman and Jewish authorities were disquieted by the threat to the establishment that Jesus and his followers seemed to offer, and they conspired successfully to execute him by crucifixion (Christianity page 198). After Jesus was crucified for the sins of all men, he was believed by Christians to have risen from the dead and then ascended to Heaven. After the death of Jesus, his life and teachings were written with many "tall tales" (as I like to call them) about the great battles and accomplishments of Christians as well as success stories about the followers of Gods" Word.
