“It is perfectly logical and reasonable to examine a position, or the progression of a position, and work out its implications. Paul himself does this to the Corinthians.
Evidently swayed by Greek philosophy, some puddingheads in Corinth denied the doctrine of bodily resurrection. Paul was appalled, and with inexorable logic worked out the implications of this view. Notice his progression, “If you are saying A, then B naturally follows, as well as C, and D, and….”
12 Now if Christ is proclaimed as raised from the dead, how can some of you say that there is no resurrection of the dead? 13 But if there is no resurrection of the dead, then [A] not even Christ has been raised. 14 And if Christ has not been raised, then [B] our preaching is in vain and [C] your faith is in vain. 15 [D] We are even found to be misrepresenting God, because we testified about God that he raised Christ, whom he did not raise if it is true that the dead are not raised. 16 For if the dead are not raised, [E] not even Christ has been raised. 17 And if Christ has not been raised, [F] your faith is futile and [G] you are still in your sins. 18 Then [H] those also who have fallen asleep in Christ have perished. 19 If in this life only we have hoped in Christ, [I] we are of all people most to be pitied. (1 Corinthians 15:12-19)
Paul works out easily nine implications of this fundamental error, all designed to show where it necessarily leads. Perhaps the errorists would have cried, ‘Paul, that’s a straw man! We’re not saying any of that!’ To this, the apostle might have replied, ‘Not yet. But this is where your premises necessarily lead.'”
