word translated as "loved" is (used, for example, in John 3:16: "for God so loved the world"), rather than the Greek word referring to sexual love, . On the other hand, Theodore W. Jennings Jr. notes that "eros does not occur either in the New Testament or in the Septuagint" and that these use to refer to "the love of a husband for his wife or even to the illicit loves of inordinate desire", including throughout the Song of Solomon. The naked youth The Gospel of Mark describes how in the Garden of Gethsemane, "A young man, wearing nothing but a linen garment, was following Jesus. When they [the Temple guards] seized him, he fled naked, leaving his garment behind." (Mark 14:51–52). The text of the naked youth is puzzling for some authors; moreover, the text only appears in Mark, which has led some commentators to allege that Mark was describing himself as the youth. The separate and non-canonical Secret Gospel of Mark—fragments of which were contained in the controversial Mar Saba letter by Clement of Alexandria, which Morton Smith claimed to have discovered in 1958—states that Jesus during one night taught "the mystery of the kingdom of God" alone to a youth wearing only a linen cloth. This has been linked to the views of an ancient group called the Carpocratians. Some modern commentators interpret it as a baptism, others as some form of sexual initiation, and others as an allegory for a non-sexual initiation into a gnostic sect. However, the authorship of Secret Mark is still a matter of debate. Some scholars find it authentic, while others consider it to be Smith's forgery, while still others believe it to be apocryphon. Celibacy Eunuchs for the Kingdom of Heaven In the Gospel of Matthew, Jesus is reported to have referred to the behavior of eunuchs to illustrate an approach to sexuality: "For there are some eunuchs, which were so born from their mother's womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven's sake." (Matthew 19:3–12) The term "eunuch" normally referred to a castrated man. Several theologians and Bible commentators have interpreted this passage as indicating Jesus's support for celibacy. The early Christian writer Origen who was purported to have interpreted Jesus' words literally, was alleged to have castrated himself as an act
