Disputation
DISPUTATION [ISBE]
DISPUTATION - dis-pu-ta'-shun: In Acts 15:2, the Revised Version (British and American) reads "questioning" for the King James Version "disputation" (Greek suzetesis). In Rom 14:1, the King James Version "doubtful disputations" becomes in the Revised Version (British and American) "decision of scruples" (Greek diakriseis dialogismon, literally, "discussions of doubts"). The Greek in neither case implies what the word "dispute" has come to mean in modern English, but rather "to discuss" or "argue."
