Do all Lutheran churches have the same view of the Book of Concord?
No. Many Lutheran churches in the world today have been thoroughly influenced by the liberal theology that has taken over most so-called “mainline” Protestant denominations in North America and the large Protestant state churches in Europe, Scandinavia, and elsewhere. The foundation of much of modern theology is the view that the words of the Bible are not actually God’s words but merely human opinions and reflections of the personal feelings of those who wrote the words. Consequently, confessions that claim to be true explanations of God’s Word are now regarded more as historically conditioned human opinions, rather than as objective statements of truth. This would explain why some Lutheran churches enter into fellowship arrangements with non-Lutheran churches teaching things in direct conflict with the Holy Scriptures and the Lutheran Confessions.
