a Jew encounters Mark

The term christology refers to thought and discourse about the nature of Jesus Christ. In my field—religious studies—and in cognate fields, there's an -ology for every Person of the Trinity: there's theology for God (theos), christology for the Christ (xristos), and pneumatology for the Holy Spirit (pneuma). Christology subdivides into two categories: high christology and low christology. In high christology, Christ is spoken of in language that affirms his godliness and divine nature. In low christology, Christ is portrayed as frail and human, subject to "the thousand shocks that flesh is heir to." The best contrast between these christologies is Jesus on the cross in the gospel of Mark versus Jesus on the cross in the gospel of John. In Mark, Jesus' final utterance is a scream: "With a loud cry, Jesus breathed his last." (Mk. 15:37) Compare this to John: "When he had received the drink, Jesus said, 'It is finished.' With that, he bowed his head and gave up his spirit." (John 19:30) The Jesus of Mark is shown suffering and dying the way any mortal would die in such a situation. In John, however, we're faced with a divine Jesus who has participated in and witnessed the fulfillment of a divine plan, as one might expect from a powerful divine being. 

In the video below, a Jew named Rebecca talks about her encounter with Mark's gospel. Rebecca doesn't talk in terms of christologies, but she has obviously understood Mark's gritty, human tone, so I think she's sensitive, in her own way, to what's going on in that gospel.

In theological academe, Mark's gospel is often jokingly referred to as "the hasty gospel" because the adverb translated as immediately (euthys) keeps recurring throughout the book. Another bit of Mark-related trivia: Chronologically speaking, it's actually the first of the four gospels and the source of many of the same verses seen in Matthew and Luke. There is another as-yet-unknown source of verses that appear in Matthew and Luke that do not come from Mark; this mysterious source has been designated Q for the German word Quelle, which means "spring" or "source." So much religious scholarship is, by the way, German.

Further New Testament trivia: The first writings of the New Testament aren't the gospels at all but rather the epistles of Paul (from roughly the early 50s to the late 60s).
