The reality is that the Orthodox share or Marian beliefs and the traditional Lutherans and Anglicans do as well.
It's incredibly arrogant for people to declare a belief held by Christianity for nearly two thousand years and believed by over two-thirds of Christians to be heretical.
No anti-Catholic bigot has EVER been able to offer a sufficient explanation as to why men such as Luther, Calvin and Zwingli not only did renounce Marian teachings, they CONTINUED to subscribe to them.
The Bible, which many Protestants DO worship, clearly says in reference to the Blessed Mother, "ALL generations SHALL call me blessed." How do the anti-Catholic bigots follow this? Do they call her blessed? NO, they spent absurd amounts of time condemning those who DO call her blessed.
I'll make the 'assumption' that the 'or' above should be 'our'. In order for the above to be true, you would need to list those beliefs of yours. I am a 'traditional' Lutheran I believe the following about Mary:
She humbled herself before God, found favor with Him.
She was 'blessed'.
The Virgin birth
She was a sinner in need of a Savior and acknowledged that fact.
She died and her soul is in heaven with the rest of the faithful dead awaiting the Second Coming of her Son like all Christians are.
