The word ‘science’ (γνῶσις) occurs only once in the NT, in 1 Timothy 6:20, and then only in the Authorized Version . The Revisers use the word ‘knowledge,’ and this gives its real meaning. The knowledge which the Apostle has in view and here condemns was a mystical interpretation of the OT, and particularly its legal parts. But the age of science, as this word is now understood, had not then arrived; and the word in its modern significance is nowhere found in NT writings.
