 Fundamental to NCF's goal was the belief that all labor in vain unless God directs our efforts – "nisi Dominus frustra".In September 1996, NCF opened Ad Fontes Academy (AFA).AFA recognizes that “each child is created in the image and likeness of God, the Creator, as a unique human being having a purpose for which he or she is created and is known by his deeds, by whether what he does is pure and right” and that “the knowledge and pursuit of truth, understanding and wisdom has the intended outcome of enabling the individual to fulfill the purpose for which he or she is created.”

When Ad Fontes Academy opened in September 1996, it started with 8 students in grades 9–10.
