In chapter 42 of his Panarion ("Against Marcionites"), Epiphanius wrote of his hope that Mary will inherit/enter the Kingdom of Heaven in the then-future, further providing evidence he did not believe in her bodily assumption:
But
let me make the point with other proofs as well. For Paul says, “Who shall lay
anything to the charge of God’s elect?”181 How can the holy Mary not inherit the kingdom of
heaven, flesh and all, when she did not commit fornication or uncleanness or
adultery or do any of the intolerable deeds of the flesh, but remained undefiled?
(f ) Therefore Paul does not mean that flesh cannot inherit the kingdom of
heaven, but means carnal men who do evil with the flesh—fornication, idolatry
and the like. (g) And your villainy has been exposed by every method, you
misguided Marcion, since the truth has anticipated you everywhere, and
safeguards the trustworthiness of the message of life. (The Panarion of
Epiphanius of Salamis Book 1 (Sects 1-46) [2d ed.; Nag Hammadi and
Manichaean Studies Volume 63; trans. Frank Williams; Leiden: Brill, 2009], 341)
