...but God sees him as righteous because he is blinded by Jesus, right?
No, not right. In fact, according to Genesis 15:6, Romans 4, Galatians 3, etc. God "reckons the righteousness" or "considers that righteousness as credited to the person's account." It is an "alien" righteousness which is given by God. See in particular Philippians 3:8.
For Lutherans, it's the Protestant Bible and Luther's various writings,
No, not correct.
The Book of Concord (1580) contains the public documents that are considered the confession of the Church:
Three Ecumenical Creeds
Augsburg Confession (1530)
Apology of the Augsburg Confession (1531)
Luther's Small Catechism (1529)
Luther's Large Catechism (1528)
Smalcald Articles (1537) [two parts]
Formula of Concord (1577) [two parts]
The two Catechisms and the Smalcald Articles are the only ones written by Luther.
I guess Lutherans are as much misunderstood as Roman Catholics.
