Of course it's pure hogwash. The whole teaching that Mary was assumed is
Then where is her tomb? Why, as a former Catholic, do you believe this is untrue?
Do you believe that Elijah was taken into heaven in a whirlwind?
That Enoch “walked with God”?
Then why don’t you believe that the Blessed Virgin Mary could have been assumed into heaven?
According to you its not just Mary’s assumption but the Eucharist etc. So go join the ranks of Rev. Moon, David Koresh, Jim Jones, Billy Graham and every other variety of mushroom sects that either have withered and died or are withering away. Strange isn’t it that the early Church Fathers who through scholarly research and the received oral tradition sorted out the various books, rejected some and included others, that we call the Bible is now denied the authority to use these very same means of theological inquiry to proclaim the Assumption.
And of course all the material in support of the Assumption dating back to the practices of the surviving Apostles are now brushed aside by simplistic interpretations that appeal to corner street Foursquare Church “theologians”
others not so much
