Protestants used to put innocent people to death as heretics and witches, just as did the Catholics.The Roman Catholics declare they only believe what the apostles taught and are the "true" church. Really? Did the apostles teach the following:
Mary was declared to be The mother of god by the Third Ecumenical Council at Ephesus in 431 AD.
This theory of Mary’s “perpetual virginity” became official dogma at the Council of Chalcedon in A.D. 451.
On December 8, 1854, Pope Pius IX declared Mary had been born without sin.
This marian dogma was proclaimed by Pope Pius XII on November 1, 1950 on his Encyclical Munificentissimus Deus.
If you do not like Roman Catholic theology, wait awhile, it will change.
It was Protestants that burned other Protestants in the witch-trials in Salem when society went insane over religious terror.
I suggest you stop pointing fingers and lick your own clean before you start working on others.
