The RCC believes Jesus' mom wasn't buried.
"We pronounce, declare, and define it to be a divinely revealed dogma: that the
Immaculate Mother of God, the ever-Virgin Mary, having completed the course of
her earthly life, was assumed body and soul into heavenly glory.
(Pope Pius XII, Munificentissimus Deus, 1950
Likewise, the Second Vatican Council taught in the Dogmatic Constitution Lumen
Gentium that "the Immaculate Virgin, preserved free from all stain of original sin,
was taken up body and soul into heavenly glory, when her earthly life was over,
and exalted by the Lord as Queen over all things."
(Catholic Encyclopedia)
There's a bit of doubt associated with that particular belief because humanity's
natural configuration is unacceptable.
● 1Cor 15:50 . . I declare to you, brothers, that flesh and blood cannot inherit the
kingdom of God, nor does the perishable inherit the imperishable.
There's also the event described by 1Thess 4:13-17 wherein it's implied that
everyone unified with Christ for the past +/- 2,000 years will be transformed all
together all at one time, which suggests to me that Jesus' mom has to wait for
that moment the same as all the rest of us to get herself an acceptable body.
