If you read Revelations, certain things need to happen, first, before the anti-christ will appear. One such thing is, Satan needs to be thrown from heaven. Once Satan leaves heaven, he only has a short time, with the anti-christ part of his final drama.
If the anti-christ has not yet come, that means Satan is still in heaven. If Satan is already the devil in hell, than the anti-christ already appeared. Most people assume the anti-christ is still to come, so that implies Satan is still in heaven. This means good and evil is not clear cut but is relative since heaven has both good; Jesus, and evil; Satan, elements. This is consistent with self righteous, even in the name of good, often resulting in doing evil; merger.
Before Satan is throw from heaven, another things will first need to occur. One such symbolism is of a divine woman in heaven, in pains of child birth. Satan is near her ready to devour her child when it is born. In 1954, the Catholic Church instituted the dogma of the Assumption of the Virgin, where Mother Mary goes to heaven, body and all, to become the bride of Christ. She is often assumed to be the church.
The Revelation symbolism of the Divine Woman sort of suggests the Assumption of the Virgin may be connected to the symbolism of the divine woman appearing in Heaven. She becomes impregnated. The Catholic church undergoes a lot of change after the 1950's, as culture changes and people become less religious. When it is time for child birth, Satan is heaven, nearby, ready to devour her child when it is born. Satan is not yet in Hell.
The Divine woman gives birth to a male child, who is protected, and caught up to the throne of God. Satan is thrown from heaven, where he pursues the Divine woman, who descends from heaven, back down to the earth. For her descent she is given the wings of an eagle, to fly to a place that is prepared for her. Satan pursues her to kill her and attempts to drown her, but the earth help the woman; she is safe. There she remains to undergo metamorphosis.
The Divine woman is also symbolized by the white lion; wisdom. In the symbolism, heaven waits until her wings are clipped and the lion is made to stand on two feet like a man, and a human mind is given to him. This symbolism suggests the divine woman is the soul of man; his female side. The wings implies, his heart is the air; not yet tangible, until he is lifted up.
When Satan realizes he can't harm the Divine women, he goes out to persecute those who maintain the testimony of Christ. The anti-christ and the lion with the wings of an eagle, are both evolving at a similar time and follow in a sequence.
