There are two possible Revised Common Lectionary texts this week. Here are links to my posts on both of them:
Use of tenses: Mark carefully selects his tenses in this passage. When
Jesus asks the question, he is using the imperfect tense, which implies
repeated action. Jesus repeatedly asks them: "Who are people
saying that am?" and "Who do you say that I am?" In our life, we will
repeatedly be asked who Jesus is.
εξ ("six"; there is a rough breathing mark, making it "hex" as in
"hexagon"; 9:2). This is the only time Mark records something as
happening "six" days later. So what happens on the sixth day? Well, on
the 6th day Jesus died on the cross! Recall the OT: On the sixth day
humanity was created. Very good (like Transfiguration). But final?
