First, early Christians displayed a general timidity toward imagery at best and engaged in the occasional full-fledged period of Iconoclasm at worst. It was not until the second council of Nicea (878) that matters were settled once and for all. After tumultuous debates, this council not only denounced iconoclasm it also called for the depictions of Christ, Mary and the saints with the admonition that when one adores an image one really adores the one represented by the image.
Second, the death of Jesus on the cross was neither expected by his followers nor was it readily embraced. Death by crucifixion was one of the worst condemnations. Roman citizens, e.g. could not be punished by crucifixion. In a sense, the cross was experienced as a scandal and an embarrassment. So they concentrated on the Resurrection, rather than on the death of Jesus.
Gradually the Christian community came to embrace the scandal of the cross as the paradox of the mystery of salvation. By the early 3rd century the cross had become closely associated with Christianity. Clement of Alexandria who died c. 215 referred to the cross as τὸ κυριακὸν σημεῖον or the Lord's sign. And according to Tertullian who died c. 225 Christians are crucis religiosi or devotees of the Cross.
Today the cross is ubiquitous and it is undoubtedly the most recognizable symbol in the entire world. We top our church steeples with crosses. We hang crosses in our homes, in our cars and around our necks. We even tattoo crosses on our bodies. Most often this is done in good faith and in good taste. Sometimes it is done in a misguided attempt at unfortunate fashion. In some instances the cross is intentionally desecrated.
Let’s take consolation in the fact that by the cross we have been saved and nothing can take that away, not even ill-advised use or worse, malicious abuse.
