Studies in the cult of Yahweh

The Secret Gospel of Mark or the Mystic Gospel of Mark (Biblical Greek: τοῦ Μάρκου τὸ μυστικὸν εὐαγγέλιον, romanized: tou Markou to mystikon euangelion), also the Longer Gospel of Mark, is a putative longer and secret or mystic version of the Gospel of Mark. The gospel is mentioned exclusively in the Mar Saba letter, a document of disputed authenticity, which is said to have been written by Clement of Alexandria (c. AD 150–215). This letter, in turn, is preserved only in photographs of a Greek handwritten copy seemingly transcribed in the 18th century into the endpapers of a 17th-century printed edition of the works of Ignatius of Antioch. Some scholars suggest that the letter implies that Jesus was involved in homosexual activity, although this interpretation is contested. In 1958, Morton Smith, a professor of ancient history at Columbia University, found a previously unknown letter of Clement of Alexandria in the monastery of Mar Saba situated 20 kilometres (12 miles) south-east of Jerusalem.
