That’s an absurdly anachronistic statement. Martin Luther was among the first to stress the idea of Sola Fide, even going so far as to regard the Epistle of James as being semi-apocryphal, which was a serious error, since it clashes with the Sola Fide concept (the Antilegomenna along with the anti-Semitic book he wrote, with vile illustrations by Lucas Cranach the Elder, are the two main objections I have to Martin Luther, although on the other hand I greatly admire his devotion to the Blessed Virgin Mary and his focus on Holy Communion as the center of Christian worship).
I would be interested to know what my dear Lutheran friend
@MarkRohfrietsch and my knowledgeable Lutheran friend
@ViaCrucis think about your idea, and likewise, what my pious Calvinist friend and fellow enthusiast of church architecture and ecclesiastical history
@bbbbbbb thinks about that statement. Because frankly, from my perspective, it seems extremely anachronistic, in that you are seeking to take a modern idea, which as far as I am aware is not even a thing in Confessional Lutheranism, and certainly not within liberal ELCA lutheranism, and you are superimposing it on the views of John Calvin, whose theology was quite different in many respects from that of Reformed Christians today (since one aspect of “Calvinists” is the idea of semper reformanda, and since the time of John Calvin there have been numerous developments, such as the double predestination concept which was developed at the Synod of Dort, birthplace of the “Tulip Idea”, and various permutaitons on Calvinism, such as early Scottish Covenanting Presbyterianism, and later on, Mercersburg Theology and Scoto-Catholicism and Reformed Catholicism, and then still more recently the Neo-Orthodoxy of Karl Barth outlined in his ponderous Church Dogmatics, a voluminous work of systematic theology which unlike Calvin’s institutes, does not make significant recourse to Church tradition or Patristics, since historically Calvinists were very much into Patristic thought and even coined the phrase “consensus patrum.”
So ideas like Lordship Salvation may be applicable to some derivatives of Calvinism in some contemporary denominations, but not so much Lutheranism, at least as far as I am aware, and certainly not if we dive into the history of the Calvinist movement.
