If you have placed your faith in Christ, you are not your last name, your financial or social status, your career, your school, or your reputation. You are Christ's. Excerpt from John MacArthur's book, Slave: The Hidden Truth About Your Identity in Christ:
"I am a Christian.”
The young man said nothing else as he stood before the Roman governor, his life hanging in the balance. His accusers pressed him again, hoping to trip him up or force him to recant. But once more he answered with the same short phrase. “I am a Christian.”
It was the middle of the second century, during the reign of emperor Marcus Aurelius. Christianity was illegal, and believers throughout the Roman Empire faced the threat of imprisonment, torture, or death. Persecution was especially intense in southern Europe, where Sanctus, a deacon from Vienna, had been arrested and brought to trial. The young man was repeatedly told to renounce the faith he professed. But his resolve was undeterred. “I am a Christian.” No matter what question he was asked, he always gave the same unchanging answer. According to the ancient church historian Eusebius, Sanctus “girded himself against [his accusers] with such firmness that he would not even tell his name, or the nation or city to which he belonged, or whether he was bond or free, but answered in the Roman tongue to all their questions, ‘I am a Christian.’ ”
When at last it became obvious that he would say nothing else, he was condemned to severe torture and a public death in the amphitheater. On the day of his execution, he was forced to run the gauntlet, subjected to wild beasts, and fastened to a chair of burning iron. Throughout all of it, his accusers kept trying to break him, convinced that his resistance would crack under the pain of torment. But as Eusebius recounted, “Even thus they did not hear a word from Sanctus except the confession which he had uttered from the beginning.” His dying words told of an undying commitment. His rallying cry remained constant throughout his entire trial. “I am a Christian.”
For Sanctus, his whole identity—including his name, citizenship, and social status—was found in Jesus Christ. Hence, no better answer could have been given to the questions he was asked. He was a Christian, and that designation defined everything about him.
This same perspective was shared by countless others in the early church. It fueled their witness, strengthened their resolve, and confounded their opponents. When arrested, these courageous believers would confidently respond as Sanctus had, with a succinct assertion of their loyalty to Christ.
Following Jesus Christ was the sum of their entire existence. At the moment when life itself was on the line, nothing else mattered besides identifying themselves with Him.
For these faithful believers, the name “Christian” was much more than a general religious designation. It defined everything about them, including how they viewed both themselves and the world around them. The label underscored their love for a crucified Messiah along with their willingness to follow Him no matter the cost. It told of the wholesale transformation God had produced in their hearts, and witnessed to the fact that they had been made completely new in Him. They had died to their old way of life, having been born again into the family of God. Christian was not simply a title, but an entirely new way of thinking—one that had serious implications for how they lived—and ultimately how they died.
