I would venture to provide my feedback for this topic. imo, there are 3 points.
1. The context and originally implied meaning.
The words may not be original. They had been changed during the process of saying-by-Jesus/ memory-by-others/writers/Greek-translation/theologically-required--modification/etc. A translation through letter by letter may not be the best approach. Just like many English idioms today, a combination of few words can produce a quite remote and different meaning against those words.
Christ-likeness is not found in the original Greek bible, AFAIK. It should be Jesus-likeness in Greek. That means we learn to be like a self-giving humble Jesus, rather than learn to be like an imaginary King-of-Kings Christ.
2. High Certainty
Some words are definitely wrong. e.g. A believer drinking poison would not be killed. I would think only some historical marketers of religions could invent this kind of words in order to attract/convince more believers.
Any publication printing this kind of statements should be banned, at least from children.
3. Criteria for authenticity
There was a voting system organised to survey/evaluate the words from Jesus. This link below provides a lot of interesting information.
Believable or not? Controversial or not? You decide!
Another 2 cents here!

... ...
The first findings of the Jesus Seminar were published in 1993 as The Five Gospels: The Search for the Authentic Words of Jesus.[4]
The Fellows used a voting system to evaluate the authenticity of about 500 statements and events. For certain high-profile passages the votes were embodied in beads, the color of which represented the degree of confidence that a saying or act was or was not authentic:
Red beads – indicated the voter believed Jesus did say the passage quoted, or something very much like the passage. (3 Points)
Pink beads – indicated the voter believed Jesus probably said something like the passage. (2 Points)
Grey beads – indicated the voter believed Jesus did not say the passage, but it contains Jesus' ideas. (1 Point)
Black beads – indicated the voter believed Jesus did not say the passage—it comes from later admirers or a different tradition. (0 Points)
A confidence value was determined from the voting using a weighted average of the points given for each bead; the text was color-coded from red to black (with the same significance as the bead colors) according to the outcome of the voting.[25]
