tn The antecedent of the Greek pronoun αὐτῷ (autō) could either be “Christ” or the “cross.” There are several reasons for choosing “the cross” as the antecedent for αὐτῷ in verse 15: (1) The nearest antecedent is τῷ σταυρῷ (tō staurō) in v. 14; (2) the idea of ἐδειγμάτισεν ἐν παρρησία (edeigmatisen en parrēsia, “made a public disgrace”) seems to be more in keeping with the idea of the cross; (3) a reference to Christ seems to miss the irony involved in the idea of triumph—the whole point is that where one would expect defeat, there came the victory; (4) if Christ is the subject of the participles in v. 15 then almost certainly the cross is the referent for αὐτῷ. Thus the best solution is to see αὐτῷ as a reference to the cross and the preposition ἐν (en) indicating “means” (i.e., by means of the cross) or possibly (though less likely) location (on the cross).
