" Jesus (as well as the authors of the gospels) would have known about Rome’s policy of sending reinforcements to the city at Passover. His decision to enter the city as he did was what we would call a planned political demonstration, a counterdemonstration. The juxtaposition of these two processions embodies the central conflict of Jesus’s last week: the kingdom of God or the kingdom of imperial domination. What Christians have often spoken of as Jesus’s triumphal entry was really an anti-imperial entry. What we call Palm Sunday featured a choice of two kingdoms, two visions of life on earth. "
