John 3:13, the Son of Man… who is in heaven?
John 3:13 ends with the Son of Man in one reading; another adds who is in heaven. The oldest witnesses do not have the clause, while the mass of manuscripts preserves its paradox.

The committee record at this verse
The APB is translated by a committee of language models that works blind. The translators are never told they are translating the Bible, never given a book name or a verse number, and never shown the witnesses listed above. Where the manuscripts disagree, the choice between readings is made before translation by the same kind of translator working the same way: it sees the competing readings and the witnesses by age and class, but never a reference or a manuscript name. There are 14,877 such places. For APB 4.0 every one was decided again in October 2026. GPT-6.1 Sol decided every one first. Claude Fable 5.1, from another model family, decided 2,483 of them second, including every place where the first translator left the base text. A departure from the base text needs both translators to agree and the first to be at least 0.8 confident. There is no third translator, so the base text stands when the two disagree. APB 4.0 is translated over those decisions. Whatever was done at this verse was done on the language and the evidence alone, and the record is public.
“The base text reads ἀνθρώπου. The copies also carry ἀνθρώπου ὁ ὢν ἐν τῷ οὐρανῷ [greek majuscule; early greek manuscript tradition; later majority tradition]; the committee kept the base text. The harder longer wording deserves weight, but the broader early evidence and plausible explanatory addition favor ἀνθρώπου.”
“The base text reads (nothing). The copies also carry ὁ ὢν ἐν τῷ οὐρανῷ. [greek majuscule; early greek manuscript tradition; later majority tradition]; the committee kept the base text. The default is strongly supported.”
The committee kept the base text without the final clause. GPT-6.1 Sol (OpenAI), the first translator, retained that text, so the unit did not go to a second translator. The textual decision states: "The harder longer wording deserves weight, but the broader early evidence and plausible explanatory addition favor ἀνθρώπου." The APB's printed John 3:13 therefore ends with the Son of Man.
The argument for each reading
If the clause entered later
The case for ending with the Son of Man rests on the early evidence and a possible explanation for the longer wording. WH and NA28 end the verse without the clause, following the earliest witnesses. The shorter reading still identifies the Son of Man as the one who came down from heaven. A later addition could have made that heavenly connection more explicit by saying that he is in heaven. This possibility explains how the clause might have entered the text, but it does not establish that this happened.
If the paradox is original
The case for retaining the clause rests on its presence in the mass of manuscripts and on the difficulty of its wording. RP and Treg preserve the statement that the Son of Man is in heaven. The clause creates a paradox: he is in heaven while speaking on earth. The committee's textual note acknowledges that the harder, longer wording deserves weight. If the clause belongs to the verse, removing it loses that explicit statement of his presence in heaven. Its wide manuscript support gives reason to take that possibility seriously, even though the oldest witnesses do not have it.
The manuscript distribution does not by itself settle how the difference arose. The clause could be an explanatory addition, while its difficult wording also gives reason to consider its retention. The uncertainty concerns an explicit statement that the Son of Man is in heaven while speaking on earth. Both readings preserve his descent from heaven. Broader doctrines do not rest on this clause alone.
