Comparing Chrisitianty and Islam



Judaism, Christianity, and Islam are three closely related religions. Because they all revere Abraham and certain other patriarchs mentioned in the Bible as their spiritual ancestors, they are called Abrahamic religions. (The Baha'i world faith is sometimes also included in this grouping.) However, their many points of similarity are no guarantee that their followers can get along. Most of the serious religiously motivated conflicts, mass crimes against humanity and genocides in the 20th century have been between Muslims and Christians. This has included genocides Bosnia Herzegovina, East Timor, and the Sudan, as well as serious conflicts in Cyprus,  Kosovo, Macedonia, and the Philippines. As of mid-2001, two of these conflicts (Sudan and Philippines) are still active, and three others are inert only because of peacekeepers on the ground.

It is difficult to compare Christianity to any other religion, because there is such a wide range of beliefs and practices among various wings of Christianity: Roman Catholicism, Eastern Orthodox churches, the Anglican communion and the tens of thousands of Protestant faith groups. Some commentators have suggested that Christianity consists of a number of different religions which share little more than the Bible and the name of their religion. Protestant Christianity is obviously divided into at least liberal and conservative wings---divisions which hold few beliefs in common. Some of the descriptions below will thus necessarily be somewhat simplistic and lacking in precision.

  1. The Christian church is normally considered to have begun at Pentecost, 50 days after Christians believe that Jesus was executed. Unfortunately, the year of his death is unknown.
  2. Most religious historians view Islam as having been founded in 622 CE. However, many if not most of the followers of Islam believe that:
    bullet Islam existed before Muhammad (pbuh) was born.
    bullet The origins of Islam date back to the creation of the world.
  3. Muslims traditionally acknowledge respect for Muhammad, Jesus and other prophets (peace be upon them) by adding this phrase or an abbreviation "(pbuh)" after their names.
  4. Greg H. Parsons, Executive Director, "U.S. Center for World Mission," Pasadena, CA; quoted in Zondervan News Service, 1997-FEB-21.
  5. One exception is the Nation of Islam which promotes a black supremacist ideology. For example, leader Louis Farrakhan stated that "White people are potential humans…they haven’t evolved yet." (Philadelphia Inquirer, 2000-MAR-18). However, most Muslims do not consider the Nation of Islam to be part of Islam, because of its unique beliefs about God, humanity and the rest of the universe.
