“It seems that the age of the earth IS a major issue. How can a OEC and YEC find common ground when the YEC denies the what the other believes?”
Well, the enemy of my enemy is my friend :)
Both OEC and YEC agree with each other on fundamental principles that unite us, which are much more important to us both than any of the little issues we may squabble about.
I have seen several YEC'ers here condemn anyone that believes the earth to be older than that which the 'Bible states'.
Oh. You are willing to compromise your faith to align with a group that denies your faith?
