Nearly every doctrinal difference between the Lutheran and Eastern Orthodox Churches stem from two factors. 1. The Lutheran Church is a catholic, or western Church which shares its roots with the Roman Catholic Church. The forefathers of the modern Orthodox and the forefathers of the modern Roman Catholic and Lutheran Churches underwent the "Great Schism" in the first millennium over Trinitarian doctrine and 2. The Orthodox uphold Apostolic Tradition as a separate means of Church authority, while the Lutheran Church only accepts those tenets of Church Tradition which are upheld by the authority of the Canonical Scriptures. Both are liturgical, historic, sacramentarian Churches. During the Lutheran Reformation, there was much dialogue between the Greek Orthodox and Lutheran theologians as many of their grievances with Roman Catholicism are the same. There were some small, political and doctrinal issues which prevented any formal declaration of union or fellowship. Dialogue continues, and many of the differences between these two historic Churches are simply cultural.
The main difference is the authority of the pope. Catholics accept it, Protestants and Orthodox don't. There are some differences in the cannon (list of books) included in the Old Testament (although they all have the same New Testament). There are several different types of Protestant religions (Lutheran, Methodist, Anglican, etc) which have differences between themselves and differences between Catholic/Orthodox. So complicated to get into more specifics.
The difference is between truth (Orthodox) and error (Baptists).
Lutheran Bible has 66 books and Catholic Bible has 73 books. There is no difference in the New Testament of Catholics and Lutheran. However, Catholics consider 7 more books as divine in the Old Testament of the Bible.
Religion is the human expression towards supernatural being but theology is the study of God's nature.
Orthodox Jews abide by the commands of the Torah and the Oral Torah (Talmud).
The synods of the Lutheran Church represent different regions of the country. Each synod may have different doctrines, as well.
For a very thorough answer, from a Presbyterian perspective, read Charles Hodge, Systematic Theology, and look up Luther, and Lutheran Doctrine in the index. There you will find a well done treatment of each doctrinal difference, backed up with scriptural citations, and lots of reasoning to explain his interpretations. Hodge was a genius, pious, and respectful (especially of other's views). It's important to remember that there are after all, very few differences between Lutherans and Presbyterians.
Mainly the major difference between the two is that the Serbians are of the Eastern Orthodox Faith, and the Croatians are Catholics.
The Mystical Theology of the Eastern Orthodox Church is a book by Vladimir Lossky published by St. Vladimir's Seminary Press. Their website states:Vladimir Lossky established himself as one of the most brilliant of Orthodox scholars in the years between his departure from Russia and his death in 1958. His uncompromising faithfulness to Scriptural and patristic tradition, coupled with his constant concern for an articulate Orthodox witness in the West, makes his works indispensable for an understanding of the theology of the Eastern Church today.In this classic study of Orthodox theology, Lossky states that "in a certain sense all theology is mystical, inasmuch as it shows forth the divine mystery: the data of revelation "the eastern tradition has never made a sharp distinction between mysticism and theology, between personal experience and the diving mysteries and the dogma affirmed by the Church." The term "mystical theology" denotes the realm of human experience, that which is accessible yet inaccessible; those things understood yet surpassing all knowledge.(http://www.svspress.com/product_info.php?products_id=162)
Catholics don't squat 350.
Hasidim are a portion of Orthodox Jews. They follow Judaism on a strictly Orthodox level.
A: There are many differences between Greek Orthodox Church and Russian Orthodox Church, so posing the question that broadly is meaningless. Regular Christianity is too heterogeneous if at all useful notion.
