FIVE FUNDAMENTALS OF THE FAITH
There are five fundamentals of the faith which are essential for Christianity, and upon which we agree:
1. The Deity of our Lord Jesus Christ (John 1:1; John 20:28; Hebrews 1:8-9).
2. The Virgin Birth (Isaiah 7:14; Matthew 1:23; Luke 1:27).
3. The Blood Atonement (Acts 20:28; Romans 3:25, 5:9; Ephesians 1:7; Hebrews 9:12-14).
4. The Bodily Resurrection (Luke 24:36-46; 1 Corinthians 15:1-4, 15:14-15).
5. The inerrancy of the scriptures themselves (Psalms 12:6-7; Romans 15:4; 2 Timothy 3:16-17; 2 Peter 1:20).

And those who disagree with any of the above doctrines are not Christians at all. Rather, they are the true heretics.
So disagreements are perfectly acceptable within the confines of Christianity, because our salvation does not hinge upon doctrines other than the above five.
