Am I a Lutheran or a Christian?

Image result for George, the Margrave of Brandenburg“I was not baptized in the name of Luther, he is not my God and Savior.  I do not believe in him, and am not saved by him;  and therefore, in this sense I am no Lutheran.  But if I be asked, whether with my heart and lips I profess the doctrines which God restored to light through the instrumentality of his blessed servant, Dr. Luther, I neither hesitate nor am ashamed to call myself a Lutheran.  In this sense I am, and as long as I live, will remain a Lutheran.” Amen, and amen to this.
