Every reference to the "cross" and "crucifixion" in the entirety of the New Testament is applicable to one of the five categories: (1) the material object of the cross (2) the historical event of Christ's crucifixion on the cross (3) the theological significance of Christ's crucifixion on the cross (4) the Body of Christ's spiritual identification with Christ's crucifixion (5) the figurative usage of "taking up a cross."
