August 13, 236 AD - Hippolytus Martyred
Second century theologian Hippolytus wrote against the Gnostic heretics who had infiltrated the early church, and he did so with serious credibility. He was a disciple of Irenaeus of Lyon, who was a disciple of Polycarp, who was a disciple of the Apostle John. Because of his good work, after Hippolytus died a martyr on August 13, 236 AD, he was revered as a saint of the early church despite his writing against the inerrancy of the Pope.
