1 Corinthians 15:13-15

New Catholic Bible

¹³ If there is no resurrection of the dead, then Christ has not been raised. ¹⁴ And if Christ has not been raised, then our preaching is useless, and so is your faith. ¹⁵ We are even false witnesses to God, for we testified that he raised Christ when he did not raise him up, assuming it is true that the dead are not raised.
