VI. Mary’s Assumption into Heaven
Gen. 5:24, Heb. 11:5 – Enoch was bodily assumed into Heaven without dying. Would God do any less for Mary the Ark of the New Covenant?
2 Kings 2:11-12; 1 Mac 2:58 – Elijah was assumed into Heaven in fiery chariot. Jesus would not do any less for His Blessed Mother.
Psalm 132:8 – Arise, O Lord, and go to Thy resting place, Thou and the Ark (Mary) of Thy might. Both Jesus and Mary were taken up to their eternal resting place in Heaven.
2 Cor. 12:2 – Paul speaks of a man in Christ who was caught up to the third Heaven. Mary was also brought up into Heaven by God.
Matt. 27:52-53 – when Jesus died and rose, the bodies of the saints were raised. Nothing in Scripture precludes Mary’s assumption into Heaven.
1 Thess. 4:17 – we shall be caught up in the clouds to meet the Lord in the air and so we shall always be with the Lord.
Rev. 12:1 – we see Mary, the “woman,” clothed with the sun. While in Rev. 6:9 we only see the souls of the martyrs in Heaven, in Rev. 12:1 we see Mary, both body and soul.
2 Thess. 2:15 – Paul instructs us to hold fast to oral (not just written) tradition. Apostolic tradition says Mary was assumed into Heaven. While claiming the bones of the saints was a common practice during these times (and would have been especially important to obtain Mary’s bones as she was the Mother of God), Mary’s bones were never claimed. This is because they were not available. Mary was taken up body and soul into Heaven.

[T]he Apostles took up her body on a bier and placed it in a tomb; and they guarded it, expecting the Lord to come. And behold, again the Lord stood by them; and the holy body having been received, He commanded that it be taken in a cloud into paradise: where now, rejoined to the soul, [Mary] rejoices with the Lord's chosen ones..."
—Saint Gregory of Tours, Eight Books of Miracles,1:4(inter A.D. 575-593),in JUR,III:306
"There was need that the body of her who in childbirth had preserved her virginity intact, be preserved incorrupt after death. There was need that she who had carried her Creator as a babe on her bosom, should linger lovingly in the dwelling of her God. There was need that the bride whom the Father had betrothed to Himself should live in the bridal chamber of Heaven, that she who had looked so closely upon her very own Son on the Cross, and who there felt in her heart the sword-pangs of sorrow which in bearing Him she had been spared, should look upon Him seated with His Father. There was need that God's Mother should enter into her Son's possessions, and as a Mother of God and hand- maid, be reverenced by all creation."
