<many people heard HIS VOICE, yet because of their wrong understanding of HIS VOICE, left HIM>

CHRIST SAYS "MY sheep HEAR MY VOICE", not "my sheep hear my voice but some have a wrong understanding of me because i'm not clear and leave". You're confused again Brian T with all that cultism that has been pushed on you all these years. CHRIST'S "VOICE" is clear when heard. Men either choose to "HEAR AND BELIEIVE" or to hear and "BELIEVETH NOT".

<why do you accept the NEW TESTAMENT as "THE WORD OF GOD" when "THE WORD OF GOD" SAYS nothing about IT?>

Clearly you don't, and until you repent and "HEAR HIS VOICE" from "THE WORD OF GOD" which you admittedly here reject, you'll never know.

<why do you agree with catholics on the defintion of the New Testament?>

you mean why do catholics, who "believeth NOT", like yourself, try to make claim that they believe what "IS WRITTEN" in "THE WORD OF GOD"??? While their "FRUITS" of evil evidence otherwise?
No need to play your roman catholic games here cultist.
