Ancient Byzantine artists contributed a spectacular art form to Christian history by creating mosaics of biblical characters and stories, along with Christian signs and saints. Mosaicists pieced together tesserae—small pieces of stone, marble, or glass—to create enormous images on church walls, ceilings, and floors. Visiting a Byzantine church merits constant neck craning, looking up and down, at these intricate creations.
In 549 AD Archbishop Maximianus consecrated Ravenna, Italy’s new basilica, Saint Apollinare en Classe. He named the building after Saint Apollinare, an early martyr and the first Bishop of Ravenna, allegedly appointed by the apostle Peter himself. Walking up the nave, visitors gaze increasingly upward as they approach the apse image of Saint Apollinare with outstretched arms, flanked by the sheep of Christ’s flock. It’s a fitting tribute to a holy man who endured repeated beatings for his faith and persistent ministry to Christians.
However, a dominant image looms above the revered bishop, indicating its preeminence. It’s a large, gemmed cross with a small bust portrait of Christ positioned at the axis. Perhaps the mosaic’s designer wanted to remind worshipers that even our most devout service and sacrifices cannot compare to Christ’s sacrificial victory. He wanted us to remember the meaning and mystery of the cross.
Early Christians and the Cross
When I began studying early Christian art at mid-life, I discovered how much ancient believers revered Christ’s cross. They felt compelled to touch, honor, and memorialize it. Christians passed along stories about its power, history, and mystery. They replicated the cross in humble homes and grand basilicas, on catacomb walls and stone sarcophagi. Still, they knew the Savior, not the actual cross itself, had ushered in salvation and radically changed their lives. The sign of the cross prompted them to remember, follow, and glorify the Lord. This simple sign increased their devotion to Christ.
As obvious as this cross appreciation seems, as a Protestant I hadn’t encountered many of the long-established art, signs, legends, rituals, festivals, and extra-biblical stories related to Christ’s cross. Not because I didn’t care; for the most part, I didn’t know they existed. My church tradition hadn’t taught them. As I sat in the classroom and studied at home, I thought: This is fascinating. Has this information been here all along? Why haven’t I heard about this? I had lots of catching up to do. I wanted to understand the breadth of early Christianity and its relationship to the cross, the faith’s core and widely known symbol.
As I researched and studied further, art and history about the cross both inspired and surprised me. The horror and audacity, simplicity and splendor, reverence and sincerity, captured my imagination. Early Christians so honored the cross, Byzantine religious leaders banned its image in floor mosaics so it wouldn’t be stepped on. Somewhere in church history we’d misplaced this sacredness, and perhaps the earliest Christians guarded what we’ve now lost. On the other hand, certain stories and practices stretched me too far. I couldn’t believe the superstitions or every extra-biblical story. Nor could I condone later abuses that pedaled the cross for money and miracles. Then and now, kitschy crosses outnumbered the liturgical ones. Still, somewhere in between, early Christians taught me remarkable, life-changing lessons about the cross.
When I shared sign-of-the-cross anecdotes with friends and family, they usually responded by saying, “I didn’t know that.” Or, “It’s interesting. Tell me more.” As a result, I wrote The Mystery of the Cross. It begins by addressing pre-Christian crosses and then the cross-related art, life, and worship of early believers during the first millennium. The chapters are both informational and devotional, prompting you to consider not just the early Christians, but the cross’s influence on you, too. Perhaps what you read will also be transformational.
Ancient Cross, Contemporary Life
If you haven’t considered the cross beyond weekend worship, tapping into these images and stories can broaden and deepen, renew or strengthen, your commitment to Christ. Exploring the art, uses, history, and mystery of the cross can validate its centrality to the Christian faith. Meditating on its enduring meaning can help apply its power and principles to everyday matters.
Accordingly, The Mystery of the Cross invites you to read intriguing stories about the sign of the cross, ponder their meaning, and consider how these anecdotes speak to you. The 40 short chapters can be read for art appreciation, historical information, personal meditation, spiritual formation, small-group discussion, Lenten observation, and worship insights. Whatever the use, The Mystery of the Cross can help you understand and appreciate the cross’s spiritual work in the world and its power for everyday life.
Most of all, I hope this book witnesses mystery. The apostle Paul wrote about the gospel’s mystery, revealed through Christ and his death on the cross. Irenaeus, a second-century church father, described it when he explained, “By means of a tree, we were made debtors to God. Likewise, by means of a tree [the cross], we can obtain the remission of our debt.” Beyond glorious art, ancient history, and intriguing anecdotes, the cross stands as a symbol of salvation. For reasons beyond my comprehension, the mighty God stooped to conquer evil and forgive sin. This is his eternal commitment. This is the inexpressible value and mystery of the cross.
