What do Christians believe? Answering this question is no simple matter. Christianity in general encompasses a wide range of denominations and faith groups. Thus, within the broad umbrella of Christianity as a religion, Christian beliefs vary widely as each denomination subscribes to its own set of doctrines and practices.

Definition of Doctrine

Doctrine is something that is taught; a principle or creed of principles presented for acceptance or belief; a system of beliefs. In Scripture, doctrine takes on a broader meaning. In the Evangelical Dictionary of Biblical Theology this explanation of doctrine is given:

"Christianity is a religion founded on a message of good news rooted in the significance of the life of Jesus Christ. In Scripture, then, doctrine refers to the entire body of essential theological truths that define and describe that message ... The message includes historical facts, such as those regarding the events of the life of Jesus Christ ... But it is deeper than biographical facts alone... Doctrine, then, is scriptural teaching on theological truths."

Christian Creeds

The three major Christian creeds, the Apostles' Creed, the Nicene Creed, and the Athanasian Creed, together constitute a fairly comprehensive summary of traditional Christian doctrine, expressing the fundamental beliefs of a wide range of Christian churches. However, many churches reject the practice of professing creeds, even though they may agree with the content of the creeds. They refuse to accept or acknowledge the creeds in a desire to follow no text except that which is written in the Bible.

Major Christian Beliefs

While many theological differences exist among Christians, most hold a set of beliefs in common. C.S. Lewis explores this common core of Christian beliefs in his book Mere Christianity. These positions deal with how God reveals himself and relates to humans; the character of God; God's plan of salvation; God's design for the church; and end times events.

The following beliefs are central to almost all Christian faith groups. They are presented here as the core beliefs of Christianity. A small number of faith groups that consider themselves to be within the framework of Christianity do not accept some of these beliefs. It should also be understood that slight variances, exceptions, and additions to these doctrines exist within certain faith groups that fall under the broad umbrella of Christianity.
