The author of Hebrews wants to press on beyond basic Christian doctrine. He does not want to abandon this foundation, but he does want to build on it. That foundation is repentance from religion, faith in God, the meaning of the Levitical washings or baptisms in the Law, the laying on of hands, the resurrection, and eternal judgment. He is not content with his readers remaining in an infantile state–he intends to press on.

This is important because remaining in the foundational doctrines without pressing on creates the temptation toward apostasy. Those who have been initiated, who have tasted, but who do not press on to know Christ further are in grave danger. Sticking with the basics only is therefore not a good way to stick to the basics.

This is the central problem with pietistic fundamentalism; at the end of the day it is counterproductive and does not defend the things it seeks to defend. The real way to “defend” a foundation is by building on it.
