And the reality is that most of the beliefs that Protestants condemn Catholics for are SHARED by Lutherans (many Marian beliefs, the Real Presence, the Sacraments, including Confession).
Also, no Lutherans practice private confession. We practice a general confession. But private confession to a pastor, inside a little booth, that we do not do. I believe the church, in the Lutheran Confessions, still supports the notion of private confession, but it is not considered a sacrament nor is it at all practiced by any Lutheran body that I've ever heard about. Sacraments in the Lutheran Church are believed to be only those that contain some outward sign - Baptism (the water) and the Lord's Supper (bread & wine).
