In the beginning was the Word, and the Word was with God, and the Word was God. 2He was in the beginning with God. 3All things came into being through Him, and apart from Him nothing came into being that has come into being. 4In Him was life, and the life was the Light of men. 5The Light shines in the darkness, and the darkness did not comprehend it. (John 1:1-5)
And the Word became flesh, and dwelt among us, and we saw His glory, glory as of the only begotten from the Father, full of grace and truth. (John 1:14)

Yep, denial of Scripture, also known as the Word of God, is denial of Christ, and will send a person to hell.
Jesus is the Word. Scripture is inspired by God but is NOT Jesus. You do understand the difference don’t you?
Which jot or tittle in Scripture is not the Word of God?
Well, not really. I go by what the Holy Spirit wrote, not what may seem logical to my fallen human mind. And then there's this:
I will worship toward thy holy temple, and praise thy name for thy lovingkindness and for thy truth: for thou hast magnified thy word above all thy name. (Psalm 138:2)
So now we also see that God magnifies His word to the level of His name.
So not only does God call Jesus the Word of God, He also exalts His Word above His own name. And you don't think there is an eternal price to pay for man to deny any part of it?
By the way, which parts of Scripture have you determined to be optional?
