Purgatory denies the power of God and the completeness of the sacrifice of Jesus.
Mariology = "discourse about Mary", or "account of Mary" -- generally "conversation about Mary's role, if any, in salvation." How the existence or use of the term could be blasphemous escapes me. To say, "Mary has no role in salvation," is to engage in Mariology.
I can handle your own personal interpretation of Scripture, but your own personal interpretation of English and your own personal interpretation of what the Church teaches ... well it's that kind of nonsense that has led me to back off from conversations here.
So many of the protestant attacks begin with erecting a straw man that after a while I wonder whether there is any interest in truth at all. Certainly, when the argument begins with falsehood and relies on bullying, insult, and perseveration the natural conclusion is that even if the antagonist believes there is a truth, he doesn't much believe in the Truth's power to vindicate Himself.
“To say, “Mary has no role in salvation,” is to engage in Mariology.”
No one holding that belief is engaging in Mariology. One sentence does not make a study - and Mariology is “The body of belief or dogma or the systematic study of the Virgin Mary and her role in the Incarnation.”
If you feel the need to make a systematic study of the Virgin Mary, then you have already lost the focus Jesus demanded.
“27 As Jesus was saying these things, a woman in the crowd called out, “Blessed is the mother who gave you birth and nursed you.” 28 He replied, “Blessed rather are those who hear the word of God and obey it.”
It isn’t that Mary is a bad person - far from it. But to pay serious attention to Mary is to miss the boat on what makes her important - Jesus!
Jesus doesn’t even call her “Mother” in scripture. Not once. He calls her, “Woman”. I don’t believe for a moment that he was being disrespectful of her. I think he is guarding against the heathen tendency to make more of her than God wanted.
Now look at the incredible statement I posted by the Pope:
“Let all, therefore, try to approach with greater trust the throne of grace and mercy of our Queen and Mother, and beg for strength in adversity, light in darkness, consolation in sorrow; above all let them strive to free themselves from the slavery of sin and offer an unceasing homage, filled with filial loyalty, to their Queenly Mother. Let her churches be thronged by the faithful, her feast-days honored; may the beads of the Rosary be in the hands of all; may Christians gather, in small numbers and large, to sing her praises in churches, in homes...”
Mary doesn’t give grace or mercy - God does. You cannot free yourself from the slavery of sin - God does that. Offer unceasing homage? Let HER churches be thronged? May Christians gather to sing her praises?
That is blasphemy, and is obscene to anyone who worships God.
