Lutheran (noun) vs. Lutheran (adjective)
In answer to your question, Dustin, being Lutheran has to do with being a Christian whose sole hope is the Gospel, who has a theology of the Cross rather than Glory (that is, grows closer to Christ in the experience of weakness, suffering, and defeat rather than strength, power, and victory), who has a sense of vocation (that God is in the ordinary tasks of life that He calls us to), who recognizes the depths of human sin and also the depths of God's grace... Someone with at least some of these characteristics I describe can be said to be, figuratively and at least some degree, Lutheran.
Yes, I am aware that Dostoevsky is not a member of the Lutheran Church-Missouri Synod and that I could not commune with him and he certainly would not commune with me. Yes, I know he was a member of the Russian Orthodox church. But you don't see much salvation by works or even by piety in Dostoevsky's novels. There is a sense in which you don't have to be a Lutheran (noun) to be Lutheran (adjective) . (There is also a sense in which not all Lutherans are Lutheran.)
