You bear false witness against about a billion people with stunning facility.
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 was a catholic, my entire family were and most still are catholics, ask them what the immaculate conception is and that is what they’ll tell you. Ask them if they’re going to heaven and they say yes, ask why, and they say “I’m a good person” everytime .... It speaks for itself ...
