Greek Apologist

Saint Justin was born in Palestine and became one of the most important philosopher in the early Christian church.

He studied Stoic and Platonic philosophy and he was the first Christian writer to bridge the gap between faith and reason. In his writings the Old Testament and Greek philosophy met to form the single stream of Christianity.

Three of his many books are still in existence: two 'Apologies' and a 'Dialogue with the Jew Tryphon'.
St.Justin opened a Christian school in Rome. He was later beheaded, because of a Roman law against his religious beliefs.
