"The fact is, American Christianity has historically been focused so obsessively on the Nicene Creed -- which says Jesus was the son of God, who was crucified for our sins and rose from the grave three days later -- that it never made much room for the actual teachings of this radical Jewish street preacher.
This is why I'm against Easter. It celebrates the death of Jesus nearly to the exclusion of his life. If the Easter miracle can save us from this life, then why bother with the harder work of enacting the kingdom of God here? It is, after all, much harder."
If there is no Easter, there is no kingdom of God. There would be no King in the kingdom. No power, no authority for the kingdom to advance.
American Christianity should take its lumps on the chins for some of its problems, but being to rooted to the historic orthodoxy really isn't one of them.
