Although the text of NA27 and UBS4 is supposed to be identical, apparently some inconsistencies remain.
Perhaps this has been caught previously, but I noticed today in 1Cor 9:1 that EWRAKA is read by UBS4 (also BYZ/TR), while EORAKA is read by NA27 (also WH), the orthography varying according to the "Attic" versus the "normal" form.
Was this an oversight in one or the other Muenster-based editions? Can we expect it to be corrected in the next edition (whichever one will be held to reflect the original orthography)? Are there any other cases of textual (not punctuational) difference between NA27 and UBS4?
