I Corinthians 13:8-10 proves the miraculous gifts that were available in the first century are not still in operation today. The text reads “Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away. For we know in part, and we prophesy in part. But when that which is perfect is come, then that which is in part shall be done away.”
The word “perfect” (whole) in verse 10 doesn’t refer to “without blemish” here as much as it does “completeness.” Notice the following definitions for this Greek word from standard Bible dictionaries:
• reached its end, finished, complete, perfect (Vine’s, p.173)
• wanting nothing necessary to completeness (Thayer, p.618)
And according to Thayer (p.401), “part” in verse 9 means “One of the constituent parts of the whole. Universally in a context where the whole and its parts are distinguished, Luke 11:36 …”
Notice the verse Mr. Thayer gives to illustrate his definition – Luke 11:36 – “If thy whole body … be full of light, having no part dark …” Having no part of what? The body. How do we know? Because since the whole and its parts are being distinguished, the part would be of the same nature as the whole. The whole is the body, therefore the part must be part of the body.
Similarly, in I Cor 13:9-10 (… For we know in part, and we prophesy in part. But when that which is perfect is come, then that which is in part shall be done away), the whole and its parts are being distinguished. The perfect (complete or whole) is being contrasted with the parts of that whole. The existence of this contrast indicates the whole is of the same nature as the part (like in Luke 11:36).
Since the parts (prophecy, word of knowledge, tongues) have to do with the revelation of God’s New Testament law, and since the whole must be of the same nature as those parts, then the whole must be the whole revelation, that is, the completed New Testament.
And since the parts were to be “done away” when the perfect came, therefore the parts (including prophecy and tongues) were done away when the New Testament was completed.
Do you see how that conclusion follows from the contrast God makes in I Cor 13:8-10?
