Faithful Sayings

"What is truth?" was Pilates cynical reply to Jesus when the King of Kings revealed He came to testify to the Truth. Jesus clearly established the Word of God as Truth (Jn. 17:17), and claimed to be the embodiment of that Truth (Jn 14:6). He is the final revelator of Truth (Heb. 1:1), so why so much ballyhoo about Truth being relative, or even non-extstent? Everyone believes in some truth, but what are holding to (if anything) as the standard of Truth?
