All Christians are dead, in the ground. We all, dead and live alike, await Christ’s return, where “the dead in Christ will rise first”.
We are NOT to pray to other human beings, inclusive of Mary. This is dangerous theology.
No, this is "dangerous theology," and I wonder what authority you can cite for your Commandment.
Who says that Mary is dead in the ground. Do you not know of the assumptions of Enoch, Elijah and the Blessed Virgin Mary into heaven.
Enoch and Elijah accounts are in the Bible. The Bible isn’t about the Blessed Virgin Mary — it’s about Christ. That’s why the Assumption of Mary is not in the Bible.
BTW — What were Mary’s last words recorded in the Bible? Hint — at the Wedding of Cana.
So your statement about ALL bodies being dead and in the ground is false, even if you are a sola scriptura fanatic.
