Let's look at this verse together...
Hebrews 6:1-2
1Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,
2Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment.
If we are to take this as listing the essentials of the Christian faith we see the following as being essential:
Repentance
Faith in God
Baptism
Laying of Hands
Resurrection of the Dead
Eternal
Judgment
I'd like to point out that no one disagrees that God will issue eternal judgments upon all men. What's at issue is the nature and purpose of those judgments.
