The Early Martin Luther Opposed Lordship Salvation

Martin Luther

 Thus you see how rich a Christian is, that is, one who has been baptized! Even if he would, he could not lose his salvation, however much he sinned, unless he refused to believe. For no sin can condemn him save unbelief alone. (The Babylonian Captivity) 

Amsdorf also said contrary to Major (who taught a kind of Lordship like view):

“All those who teach and write that good works are necessary for salvation are going directly against Luther, yes, directly against themselves."

now, Luther in his quote does mention baptismal regeneration, however Luther's system of baptismal regeneration is not the same as commonly held by many groups today, for Luther Baptism regenerates because God gives faith during Baptism to infants, he viewed it as a way to "preach the gospel" to infants. It is admittedly weird, however it is not equally bad as many modern forms. Yet, this quote shows that Martin Luther in his early days taught that faith alone is truly sufficient.
