Justin Martyr, also known as Saint Justin (c. 100 – 165 AD), was an early Christian apologist, and is regarded as the foremost interpreter of the theory of the Logos in the 2nd century. He was martyred, alongside some of his students, and is considered a saint by the Roman Catholic Church, the Anglican Church, and the Eastern Orthodox Church. Most of his works are lost, but two apologies and a dialogue did survive.
