Since death is a consequence of sin, it was fitting that in the case of Our Lady, due to her freedom from original sin and personal sin, she would have protected her from the general law of death.
The Feast of the Assumption of the Blessed Virgin Mary commemorates the death of Mary and her bodily assumption into Heaven, before her body could begin to decay.
The Assumption of the Blessed Virgin Mary is declared as a dogma in the Catholic Church stating "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." As a dogma, the Assumption is a required belief of all Catholics; anyone who opposes their belief in the dogma, Pope Pius declared, "has fallen away completely from the divine and Catholic Faith."
And Mary said:
'My soul proclaims the greatness of the Lord
and my spirit exults in God my saviour;
because he has looked upon his lowly handmaid.
Yes, from this day forward all generations will call me blessed,
for the Almighty has done great things for me.
Holy is his name,
and his mercy reaches from age to age for those who fear him.
He has shown the power of his arm,
he has routed the proud of heart.
He has pulled down princes from their thrones
and exalted the lowly.
The hungry he has filled with good things,
the rich sent empty away.
He has come to the help of Israel his servant,
mindful of his mercy
-according to the promise he made to our ancestors-
of his mercy to Abraham and to his descendants for ever.'
