Christian Beliefs

Beliefs are very important to Christianity. Doctrines about God, Jesus Christ, the Trinity, the Bible, angels and demons, and heaven and hell are among the most important. Christian denominations, although in mostly agreement on primary doctrines, can have many differences on secondary doctrines. (Go here to compare the beliefs of different Christian denominations.)

Given the great historical attention that has been devoted to Christian beliefs, the 2,000 years' worth of available writing on its many subjects, and its sometimes complex philosophical arguments, Christian doctrine can be intimidating, especially for the beginner. The following articles therefore attempt to summarize the general consensus of Christian beliefs. (See Christianity Facts and Christian Symbols and Christian denominations.)
