Your entire post is laughable and false, particularly since you are referring to Luther and others as liars. Anyone who has read Luther will understand what he said and why he said it, and your cherry-picked, out of context quote is not Luther's full teachings on the subject.
Luther was prone to overstating things to make a point. An example of this is his "sin boldly" sermon. Anyone who understands Luther (which you in your nasty anti-Protestant HATRED do not) understands that he was making a point of the full extent of Grace. He wasn't being a libertine. He was saying the shackles of Rome which caused so many in the middle ages to fear damnation if they made one small misstep (a fear Luther himself had as long as he was in the demonic institution that was 16th century Rome) you need not fear. The Grace of the Lord has taken care of all of your sins. Past, present, future. Whom the Son has set free is free indeed.
Luther, in addition to being an insane violent drunk and execrable antisemitic, was riven with scrupulosity - that psychological disorder was the spark which touched off the protestant revolution.
I am not a protestant hater. In fact, I married a proddy. (she got better)
I repeatedly make clear I do not hate protestants who have been born into their proddy families. The proddies I know follow Jesus to the absolute best of their abilities.
I do experience sadness their worship, deracinated, dessicated and devoid of Sacrifice, is not what God Himself Commanded we do, but, I understand the oral tradition of the protestant revolutionaries has, effectively, grown scales over the eyes of the sola scripturists and they are blind to the Gospel.
Only the Holy Spirit, and a humble heart, can overcome the devilish destructiveness set loose by the 16th Century Satan Mini-me's.
The proddy converts in here are estimable men and women and they have nothing but good to say about their former families and communities.
it does not work in the reverse direction , however. In fact, those who leave the Church, are but faint-hearted imitators of the hateful Herisiarch, the Lustful Lying Lunatic Luther
