Kolose 2:15

2:15 Disarming ¹  the rulers and authorities, he has made a public disgrace of them, triumphing over them by the cross. ² 

Kolose 3:4

3:4 When Christ (who is your ³  life) appears, then you too will be revealed in glory with him.

[2:15]  ¹ tn See BDAG 100 s.v. ἀπεκδύομαι 2.

[2:15]  ² tn The antecedent of the Greek pronoun αὐτῷ (autw) 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 (tw staurw) in v. 14; (2) the idea of ἐδειγμάτισεν ἐν παρρησία (edeigmatisen en parrhsia, “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).

[3:4]  ³ tc Certain mss (B^[*^] D¹ H 0278 1739 Ï sy sa) read ἡμῶν (Jhmwn, “our”), while others (Ì⁴⁶ א C D* F G P Ψ 075 33 81 1881 al latt bo) read ὑμῶν (Jumwn, “your”). Internally, it is possible that the second person pronoun arose through scribal conformity to the second person pronoun used previously in v. 3 (i.e., ὑμῶν) and following in v. 4 (ὑμεῖς, Jumeis). But in terms of external criteria, the second person pronoun has superior ms support (though there is an Alexandrian split) and ἡμῶν may have arisen through accident (error of sight) or scribal attempt to universalize the statement since all Christians have Jesus as their life.
