In Acts 1, Jesus does exactly that--ascends as witnesses look on.
In the eschatons, Jesus describes a literal, bodily return.
The biblical test for the demonized and false doctrine is DENIAL of the bodily resurrection or denial that Christ came in FLESH.
I urge you to take great care with these concepts you have.
I know why the New Testament wasn't written by the servants of the first witness of the 1000 year reign of Christ. There is a reason that the religious minded Vatican members approved all those writings that eventually the reformists would use and be deceived by to start all those denominations of Protestant Christianity. Here is the prophecy about Christianity involved with the Beast which is the information that forms images, ideas, words, etc. in the minds of MEN ( male and female ) to build with human hands out of earthen materials. Christians built millions of false gods since then. The Roman Catholic Church and Vatican are represented as the IRON part of the feet while the CLAY represents the now 40,000 different denominations of Protestant Christianity.
Daniel 2:
36: "This was the dream; now we will tell the king its interpretation.
37: You, O king, the king of kings, to whom the God of heaven has given the kingdom, the power, and the might, and the glory,
38: and into whose hand he has given, wherever they dwell, the sons of men, the beasts of the field, and the birds of the air, making you rule over them all -- you are the head of gold.
39: After you shall arise another kingdom inferior to you, and yet a third kingdom of bronze, which shall rule over all the earth.
40: And there shall be a fourth kingdom, strong as iron, because iron breaks to pieces and shatters all things; and like iron which crushes, it shall break and crush all these.
41: And as you saw the feet and toes partly of potter's clay and partly of iron, it shall be a divided kingdom; but some of the firmness of iron shall be in it, just as you saw iron mixed with the miry clay.
42: And as the toes of the feet were partly iron and partly clay, so the kingdom shall be partly strong and partly brittle.
43: As you saw the iron mixed with miry clay, so they will mix with one another in marriage, but they will not hold together, just as iron does not mix with clay.
44: And in the days of those kings the God of heaven will set up a kingdom which shall never be destroyed, nor shall its sovereignty be left to another people. It shall break in pieces all these kingdoms and bring them to an end, and it shall stand for ever;
45: just as you saw that a stone was cut from a mountain by no human hand, and that it broke in pieces the iron, the bronze, the clay, the silver, and the gold. A great God has made known to the king what shall be hereafter. The dream is certain, and its interpretation sure."
