“I do not believe Luther worshipped Mary”
He venerated her - to what extent I don’t know - but none of us “worships” Mary so the real problem would be your understanding apparently.
“or called her the blasphemous title of mother of God”
Oh, please. Yet another Protestant anti-catholic who apparently has no idea what she’s talking about. https://en.wikipedia.org/wiki/Luther%27s_Marian_theology#Mother_of_God
“We certainly do not today.”
Because Lutherans ditched a number of things early Lutherans believed. They “evolved” and still do further and further away from historic orthodox Christianity. Ever hear of the Formula of Concord or the Book of Concord? Here’s what Wikipedia says about it:
Subsequently it was signed (subscribed to) by three electors of the Holy Roman Empire, twenty dukes and princes, twenty-four counts, four barons, thirty-five free imperial cities, and over 8,000 pastors. These constituted two-thirds of the Lutheran Church in Germany at the time. Every clergyman in the Electorate of Saxony had to either subscribe or write his objections with respect to the Formula of Concord. A rhyme was circulated [at the time]: “Write, dear Sir, write, that you might remain at the parish” (schreibt, lieber Herre, schreibt, dass Ihr bei der Pfarre bleibt). https://en.wikipedia.org/wiki/Formula_of_Concord
And here’s what was in it that they all agreed to:
On account of this personal union and communion of the natures, Mary, the most blessed virgin, did not conceive a mere, ordinary human being, but a human being who is truly the Son of the most high God, as the angel testifies. He demonstrated his divine majesty even in his mother’s womb in that he was born of a virgin without violating her virginity. Therefore she is truly the mother of God and yet remained a virgin. https://en.wikipedia.org/wiki/Luther%27s_Marian_theology#Mother_of_God
So, at one point, just about every important Lutheran on the face of the earth subscribed to the belief that Mary was the mother of God - a belief you call blasphemous.
And you don’t use that “blasphemous” title today, huh? Well, you better tell the pastor at Augsbug Lutheran Church in Shawnee, Kansas (LCMS): “So along with Paul, Peter, and John, so too, Holy Mary Mother of God prays for us sinners now, and at the hour of our death.” http://www.augsburglutheranchurch.org/sermons/2015/saint-mary.html
Or you might want to tell the pastor at St. John’s Evangelical Lutheran Church in Topeka (LCMS): “Not with Mary coming to Elizabeth, and John leaping in his mother’s womb at the sound of the voice of the mother of God.” http://stjohnlcmstopeka.org/worship/sermons/sermon20151202.php
Gee, I guess that just means the LCMS is filled with crypto-Catholics!
“But again Luther initially set out to reform the Roman Church When they would not address the issues there was no other solution than to break with Rome to follow Christ.”
No, actually the Church did reform she just did it when she was good and ready. Only someone who thinks he is more important than God and His Church would think the universe runs on his self-appointed timetable.
One could say the same about Pope Francis.
