The Barbarians were among these recruits. Ultimately these tribes and others invaded and conquered the Roman Empire. Pastor Huntley shared a brief slide show of weapons used during that time.
Prior to the fall of Rome, Christians were still heavily persecuted. However, very often these Christ followers would willingly martyr themselves both in the Coliseum as well as being crucified. Their courage and reliance on, as well as devotion to, Christ strengthened other christians and the movement as a whole. It had the opposite effect that the Romans had hoped for which was to destroy it.
During the Barbarian rule christians continued to venture where others would not. Often they could be found entering places where plagues and disease were present. In stark contrast to those fleeing these places, they would move in to care for the sick and dying.
This is the way of the Cross - people willing to die to self and live (and die) for Christ.
Mrs. Cross introduced the students in the Navigators class to the story of Perpetua, a Christian martyr whose personal account of what she went through was the first recorded account of a martyr's experience. You can read more about it. I have included a link to Christianity Today

After the class, the students went outside to the parking lot where several of them were "crucified".
