The reformation was meaningless when it comes to believers. It was never meant to be a separatist movement in which the purity of truth would prevail. No the whole resides in the very name given.... REFORM .... that which one takes and attempts to modify.
The term "Reformation" was coined because of the intent of Luther's actions leading up to, and including, the posting of his 95 Theses. But alas, the best-laid plans of mice and men... Luther's attempt at reformation led to a full-out break with Rome. Luther himself was but mixture and error in many of his beliefs and ways. Luther's significance was the inertia he created in Saxony, which spread to all of Germany before enveloping Europe. The Papacy fought back but they could not stop the success of the Gospel that Paul mentioned in Philippians:
Philippians 1:12-18 12 Now I want you to know, brethren, that my circumstances have turned out for the greater progress of the gospel, 13 so that my imprisonment in the cause of Christ has become well known throughout the whole praetorian guard and to everyone else, 14 and that most of the brethren, trusting in the Lord because of my imprisonment, have far more courage to speak the word of God without fear. 15 Some, to be sure, are preaching Christ even from envy and strife, but some also from good will; 16 the latter do it out of love, knowing that I am appointed for the defense of the gospel; 17 the former proclaim Christ out of selfish ambition rather than from pure motives, thinking to cause me distress in my imprisonment. 18 What then? Only that in every way, whether in pretense or in truth, Christ is proclaimed; and in this, I rejoice.
