His gentleness, humility, patience, and meekness they believed were offered for imitation, nor did they ever separate the ideal Christian from the real. They thought that a man's religion consisted as much in the life as in the sentiment, and had not learned to separate experimental from practical Christianity. To them the death of Christ was a great event to which all others were but secondary. That he died in very deed, and for the sons of men, none could understand better than they. Among their own brethren they could think of many a one who had hung upon the cross for his brethren or died at the stake for his God. They took up the cross and followed Christ, bearing the reproach. That cross and that reproach were not figurative. Witness these gloomy labyrinths, fit home for the dead only, which nevertheless for years opened to shelter the living. Witness these names of martyrs, those words of despair. The walls carry down to later ages the words of grief, of lamentation, and of ever-changing feeling which were marked upon them during successive ages by those who were banished to these Catacombs. They carry down their mournful story to future times, and bring to imagination the forms, the feelings and the deeds of those who were imprisoned here. As the forms of life are taken upon the plates of the camera, so has the great voice once forced out by suffering from the very soul of the martyr become stamped upon the wall. Humble witnesses of the truth; poor, dispised, forsaken; in vain their calls for mercy went forth to the ears of man; they were stifled in the blood of the slaughtered and the smoke of the sacrifice! Yet where their own race only answered their cry of despair with fresh tortures these rocky walls proved more merciful; they heard their sighs, they took them to their bosoms, and so their cries of suffering lived here, treasured up and graven in the rock forever. The conversion of Marcellus to Christianity had been sudden. Yet such quick transitions from error to truth were not unfrequent. He had tried the highest forms of Pagan superstition and heathen philosophy but had found them wanting, and as soon as Christianity appeared before him he beheld all that he desired. It possessed exactly what was needed to satisfy the cravings of his soul and fill his empty heart with the fullness of peace. And if the transition was quick, it was none the less thorough. Having opened his eyes and seen the light of the Sun of Righteousness, he could not close them. Rather than relapse into his former blindness, he gladly welcomed his share in the sufferings of the persecuted.
