In attempting to deal with sin, pain and death, Christ leaped out of time and/or back to the first moment that the above became realities. Without a doubt, the shock waves of this "quantum leap"(i.e. an abrupt change, sudden increase, or dramatic advance)can be felt today. When the Apostle Paul eloquently crowed to his brethren, "Oh death where is thy sting? Oh, grave where is thy victory?" He was feeling an aftereffect from one of these waves.
Unfortunately, apostalic revelation became biblical dogma that relegated Christ and Christianity to the first century AD. That's more or less where the various sects have been stuck for 2000 years.
Further visions and revelations beyond the 1st century were considered heresy.
