Suppose you were convinced that X couldn't have really happened, but all the evidence is in favor of the fact that it did: how would you report it? How would a secular historian with positivist biases report a miracle? He or she might deny the evidence in an ad hoc manner, or he or she might deny that the evidence points in the direction of a miracle. The former would be straightforwardly unprincipled. The latter would the use of a philosophical prejudice to interpret the evidence--and if that's bona fide history, then so is the acceptance of miracles and the resurrection.
