But it is possible, and in fact fairly common, to find Christians that do not particularly trust or value the literal text of the Bible. Perhaps because it is perceived as a text written by fallible, flawed people, or perhaps due to genuine liberal thinking.NT does have any respect for those who reject Jesus either.
Both situations are considerably difficult to establish themselves in Islaam, by design even.
As an aside, I am not very aware of those verses of the NT that would be comparable to the Qur'an regarding despisal of unbelievers. Some examples would be welcome.
