Antichrist Mark Defames the Movement

Is Mark’s Gospel fundamentally at odds with John’s Gospel on how Jesus recruited disciples (Bethany beyond the Jordan vs Sea of Galilee, disciples of John the Baptist vs Galilean fishermen)? Who were the pillars of the early movement—James, Cephas, and John—and why does Mark portray James and John as “sons of Zebedee” seeking power? Why does Mark depict the disciples as ignorant, faithless, and unable to cast out demons, while John portrays them as believing friends who understand Jesus? What is the “Messianic Secret,” and why does Mark’s Jesus repeatedly command silence while John’s Jesus says He taught nothing in secret? Why do demons identify Jesus in Mark while humans fail? Why does Mark say Jesus’ family thought He was “out of His mind,” and why does Mark add “relatives” and “household” to the “no honor” saying? Why does Mark’s timeline place Jesus eating Passover rather than being slain on the preparation day, and what does this imply about “Lamb of God” theology and Mark’s purpose?
