"and Mary's flesh is rotten in a grave."<quoted text>
Anything we do feeding the poor, helping a neighbour, etc being baptized is works we do.
Noah had God given faith ,
Noah, believed God was going to save Him from the pending flood that was to come.
The works that Noah did was build the ark, He and His family were saved. Because He exercised the faith God gave Him,.
Just like we today exercise our faith in Jesus to save us, we are in Christ like Noah was in the ark.
Catholic say Mary was the Ark,the truth is Jesus is the ark of the New Covenant.
The Ark that Noah built is rotten laying on the side of a Mountain and Mary's flesh is rotten in a grave.
Jesus never knew any decay, He is alive and is sitting on His Throne.
I will pray a Hail Mary for you.
They looked for her grave. They never found it. She was assumed into heaven like Enoch and Elijah.
"[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..." Gregory of Tours, Eight Books of Miracles, 1:4 (inter A.D. 575-593).
