Constantine-Silvanus (died 684) was the founder of the Paulicians, a Christian movement in 7th century Armenia, who sought to return to the purity of the church in the time of Paul the Apostle.
Reading the gospels and epistles caused Constantine to change his name to Silvanus, after the companion of Paul, and begin preaching, gathering around him a group of followers who rejected what they considered the image worship and superstition of the Byzantine Church.
For thirty years he traveled extensively, along the Euphrates valley, across the Taurus Mountains, and into the western parts of Asia Minor, making converts on the way.
His missionary activities came to the attention of the Byzantine Emperor, Constans II, known as Constantine Pogonatus (the bearded).
Emperor Justinian II ordered Titus and all the Paulicians to be burned to death as heretics in 690.
