The authenticity of less than 1% of the Bible is disputed. Here is a summary of these passages along with the reasons:
| John 7:53-8:11 | it is a liberal story that does not fit in its surrounding context, and which is contrary to Christian doctrine; see Essay:Adulteress Story |
| Mark 16:9-20[1] | This passage is not in the earliest manuscripts, and is not in Mark's style.[2] Mark, merely a boy at the time, was probably not communicating with the group that witnessed the risen Christ. |
| John 7:39 | "Now this he said about the Spirit, whom those who believed in him were to receive, for as yet the Spirit had not been given, because Jesus was not yet glorified." (ESV) This verse is grammatically flawed and somewhat contrary to Christian doctrine, it reads like an editor's commentary rather than in the style of this Gospel. It is contrary to Mark 3:29, when Jesus stated early in His ministry that "whoever blasphemes against the Holy Spirit never has forgiveness, but is guilty of an eternal sin.” (ESV) |
| Luke 23:34[3] | Not in the original manuscripts, this is a liberal saying inconsistent with Christian doctrine, but it does have defenders.[4] |
The authenticity of additional, isolated New Testament verses have been questioned for minor reasons like their repetitiveness or placement of a comma, which include: Matthew 17:21, Matthew 18:11, Matthew 23:14, Mark 7:16, Mark 9:44 & 9:46, Mark 11:26, Mark 15:28, Luke 17:36, Luke 23:17, John 5:3–4, Acts 8:37, Acts 15:34, Acts 24:6–8, Acts 28:29, Romans 16:24, and First John 5:7-8.
