There is the "philosophy of men" and there is the "philosophy of God" who the Greeks saw as the "Unmoved Mover"

Biblical philosophy

Just as there is the doctrines of men there is also the doctrine of Jesus. But the word of Jesus i.e. is the right reason of Jesus. That Word or Logos of Jesus, like the word of God, may or may not be a mere view of life beyond the common rational of the mind of men and therefore would be inclusive of divine revelation, rather than called merely the philosophy of man.

The Bible is one reality, knowledge, or values, based on logical reasoning" but includes revelation from unmoved mover directly to man in his heart and mind. 

Some of the philosophers of the Greeks saw the Torah as a book of philosophy for they were willing to look for the reason behind the its rituals and ceremonies for they had no vested interest in the hierarchy of what the judaic religion had become before the arrival of Christ.

Modern philosophy =

Friedrich Nietzsche's Beyond Good and Evil is one of the most influential works of modern philosophy. 

The Bible is one of the most influential works of philosophy but it goes beyond "The study of the nature, causes, or principles of reality, knowledge, or values, based on logical reasoning" but includes revelation from the unmoved mover directly to man in his heart and mind. 

Even the German philosopher, Immanuel Kant, who spoke of “that which is hidden” also believed that moral virtue was found in doing the right thing for the right reason. Who is the judge of that intent? The Bible speaks of the "knowledge of good and evil" and Friedrich Nietzsche who wrote Beyond Good and Evil.  

“The great minds who followed reason and facts most rigorously came to the conclusion that, ultimately, the essence of things is beyond logic and cannot be grasped.” ― Mattias Desmet, The Psychology of Totalitarianism
