And the Scripture gives reason for that.Ah! You are entirely wrong. I'm saying that we can't speak on what happen we can assume but we must mention its an assumption. We have no verifiable data. That verse taken literally as you've done makes God into a liar. Because Enoch has not died and neither has Elijah.
Otherwise all must die. It gives no exception for Mary.
The Assumption of Mary is as verifiable as one of the moons of Saturn made of green cheese. You can't prove either one. I'll make up my own religion just as the RCC has made up theirs with pagan doctrines. And my doctrines (such as I gave you) will be just as believable. One cannot make an argument from silence!
