And if Christ be not risen, then is our preaching vain, and your faith is also vain.
All Commentaries on 1 Corinthians 15:14 Go To 1 Corinthians 15
John Chrysostom
AD 407
Logically Paul would have said here that if Christ had not been raised, historical facts would have been denied, but instead he says something which is much more relevant and indeed frightening to the Corinthians. For if Christ had not risen from the dead, then Paul’s preaching would have been useless and their faith would have no meaning.
