Yes. Their founder helped to translate it into German.
From the question as stated, NO, as Lutherans and Calvinist are Christian.
Christian use the Bible.
Yes, there are Lutherans, Catholics, Baptists, Orthodox, etc.
Yes. Actually, Lutherans are a specific church (or denomination), while "protestants" is an umbrella term that includes many different denominations.
I do not know about Islamics, but Catholics would prefer you didn't but they won't shun you if you do. Lutherans don't really care too much. For other Christian groups I'm guessing its similar to Lutherans.
The Lutherans do not have a separate bible. They study and follow the bible that most Christians follow. There are 46 books in the Old and New Testament.
Christian Universalists use the Bible.
The name "Christian" means 'Christ-like", so if some one is a true 'Christian, then yes, they use the Bible. Where else can one find the "sayings of everlasting life" except in the Bible? (John 6:68)
Orthodox Christians use the same Bible as Catholics, Protestants, and most other Christian denominations.
they will use it to protected them from any harm that could acure in life
Catholics believe the pope is the vicar of Christ on earth, Lutherans do not. Catholics believe they are saved by faith and good works. Lutherans believe they are saved by faith alone. Catholics believe in Purgatory, Lutherans do not.
Lutherans are a mainstream Christian denomination and they regard God in the same way as all other orthodox churches like the Roman Catholics, Methodists, Baptists etc. The only difference between the Lutherans and, say, the Roman Catholics, is that, as they are a protestant Church they still uphold all Christian beliefs but do not accept the authority of the Pope nor the other members of the Roman Catholic heirarchy. Doctrine between the two churches (provided that it is Bible based) is very similar, but Lutherans do not accept man-made doctrine such as purgatory, limbo, prayer to saints as intermediaries, infallibility of the Pope, priestly celibacy and so on. But their beliefs about God are all the same.
