I am stuck with this verse in the gospel of St Luke :
"And it came to pass about an eight days after these sayings, he took Peter and John and James, and went up into a mountain to pray.
And as he prayed, the fashion of his countenance was altered, and his raiment was white and glistering. And, behold, there talked with him two men, which were Moses and Elias: Who appeared in glory, and spake of his decease which he should accomplish at Jerusalem.."
The Mount of Transfiguration has both Elijah and Moses appearing in the presence of God the Father and God the Son in glory. Moses died and Elias was translated.The righteous believers are going to receive the glorified body in the life to come,that is, after the resurrection.
The verse above seems to imply that Moses and Elias did appear with a glorified body, before Christ rose from the dead. If my understanding is correct,How could this be explained theologically?
