In the year 126, St Quadratus wrote an Apologia in defence of Christianity. Presented to the emperor Hadrian (117-138), the Apologia affected the persecution of Christians, since the emperor issued a decree saying that no one should be convicted without just cause. This Apologia was known to the historian Eusebius in the fourth century. At the present time, only part of this Apologia survives, quoted by Eusebius: “The deeds of our Savior were always witnessed, because they were true. His healings and raising people from the dead were visible not only when they were healed and raised, but always. They lived not only during the existence of the Savior upon the earth, but they also remained alive long after His departure. Some, indeed, have survived to our own time.”
St Quadratus is also commemorated on January 4.
