In the days of Diocletian, around the year 304 A.D., a pious priest of Rome named Felix, known for his virtuous and blessed life, was arrested and endured many tortures. At last the order was issued to cut off his neck on the 30th of August. On the way, a young Christian met him who longed to share with his priest the crown of martyrdom. He began to cry out in the midst of the crowds, "I confess the very same faith that this man confesses; I confess Jesus Christ Himself, and I lay down my life for His sake."
When the judges heard this, they seized him and ordered that his head be cut off along with the priest's. Since his name was not known, he was called "Adauctus," meaning "one added," because he added himself to the martyr Felix. Damasus, bishop of Rome, says:
"O, truly and in very truth you are rightly called Felix (Felix means "happy"), for you are happy; your faith was untouched, despising the prince of this world, confessing Christ, seeking the heavenly kingdom. Now, brethren, the precious faith has hastened with Adauctus, victorious, to heaven."
