The Devil Doesn’t Want You to Make the Sign of the Cross Because.

16. Remake ourselves in Christ’s image

In Colossians 3, St. Paul uses the image of clothing to describe how our sinful natures are transformed in Christ. We are to take off the old self and put on the self “which is being renewed … in the image of its creator,” Paul tells us. The Church Fathers saw a connection between this verse and the stripping of Christ on the cross, “teaching that stripping off our old nature in baptism and putting on a new one was a participation in Christ’s stripping at his crucifixion,” Ghezzi writes.

He concludes that we can view the Sign of the Cross as “our way of participating in Christ’s stripping at the Crucifixion and his being clothed in glory at his resurrection.” Thus, in making the Sign of the Cross, we are radically identifying ourselves with the entirety of the crucifixion event—not just those parts of it we can accept or that are palatable to our sensibilities.

17. Mark ourselves for Christ

In ancient Greek, the word for sign was sphragis, which was also a mark of ownership, according to Ghezzi. “For example, a shepherd marked his sheep as his property with a brand that he called a sphragis,” Ghezzi writes. In making the Sign of the Cross, we mark ourselves as belong to Christ, our true shepherd.

18. Soldier on for Christ

The sphragis was also the term for a general’s name that would be tattooed on his soldiers, according to Ghezzi. This too is an apt metaphor for the Christian life: while we can be compared to sheep in the sense of following Christ as our shepherd we are not called to be sheepish. We instead are called to be soldiers of Christ. As St. Paul wrote in Ephesians 6, “Put on the armor of God so that you may be able to stand firm against the tactics of the devil. … take the helmet of salvation and the sword of the Spirit, which is the word of God.”
