Did Jesus become the Christ on the cross, or when he came out of the Jordan River? Are there stages of Christhood?

According to Osho, there are no stages to Christhood; enlightenment happens in a single, sudden transformation. Jesus’ baptism in the Jordan broke the seed—the journey began, a first glimpse. He became the Christ on the cross, in total surrender—'Thy will be done, not mine'—when the tree fully blossomed. Initiation prepares; fulfillment arrives in one decisive moment of egolessness.
