Secundus, in his reply, without blaming Mensurius, somewhat pointedly praised the martyrs who in his own province had been tortured and put to death for refusing to deliver up the Scriptures and that he himself had replied to the officials who came to search: "I am a Christian and a bishop, not a traditor."
Mensurius also forbade any to be honoured as martyrs who had given themselves up of their own accord, or who had boasted that they possessed copies of the scriptures which they would not relinquish.
Some of these he claimed were criminals and debtors to the state, who thought they might by this means rid themselves of a burdensome life, or else wipe away the remembrance of their misdeeds, or at least gain money and enjoy in prison the luxuries supplied by the kindness of Christians.
