Ah yes, he who doesn’t believe the New Testament as we have it in the Greek is the inspired word of God uses it to attempt to denigrate one who does believe the New Testament is the word of God and trusts God completely to have kept His word.

To be a believer requires belief, not denial.
Believing that God has kept the errors that you believe is unbelief.
