Judaism and Christianity.
Even though i am not sure what you are asking when referring to a "second bible" i will attempt to help you. Several faiths use books in addition to the Bible that they consider as sacred to support their beliefs; examples Mormons and Jehovah Witnesses. The catholic faith uses a version of the Bible that is the same Bible as the protestant churches use with the exception being the Catholic Bible contains 8 books in the Old Testament that are omitted from versions of the Bible the protestant churches use. Even though this is the case both protestants and catholics agree on the central theme in the Bible; salvation is through Jesus Christ alone and the Bible is the only source where the sacred word of God to man is be found; this being true there would be no "second bible".
No religion has primarily or exclusively endorsed the New King James Bible, however, it is used in many strains of Protestant Christianity, most especially Anglicans and Episcopalians.
There are several versions that use transliterations of the the original Hebrew names in the KJV. The Restored Name King James Version and the Sacred Name Bible are both available online: http://www.sacrednamebible.com/
There are no other books. However, you can find books of Apocrypha which are not part of the 66. Some religions use them and even include them in their Bible. In addition, you can find even more remote books which most do not consider Holy.
As long as there are people of faith, the Bible will be relevant. It may be evident that some even of those who claim to be devout believers do not really use the Ten Commandments or the teachings of Jesus as their personal guide to ethical behaviour. If this were not the case, we would not need so many laws to enforce proper conduct. Nevertheless, Christians do still use the Bible as a source of inspiration to their faith. Even to atheists and followers of other religions, the Bible remains relevant purely because of its historical significance.
No. There are numerous polytheistic faiths and aboriginal faiths (in the Americas and Australia) without any sacred book.
The Holy Bible is from God and it helps people to become aware of what He wants for their lives. Religions would be different without scripture because, the information might not get passed on correctly if it was only taught verbally without a text.
They were not "Sacred" in the same way that you use the term (general christian type definition) as in the "Bible is Sacred" etc. Bison were honored and respected as a 'gift' from the great spirit to nourish his red children, but they were not sacred. The use of terms between these religions can cause confusion.
All religion's texts aren't sacred. Don't let anyone ever tell you they are. Saying their texts are sacred is just one of the many tools those in religious power use to protect and perpetuate their world standing. Don't play into it.
Yes, Jehovah's Witnesses use the Bible as their primary religious text.
The sacred text that the Amish use is the Bible. Those of the Amish faith are Christian. The Amish also have a set of rules governing how they should live their lives, this set of rules is called the Ordnung.
You can use the word "sacred" to describe something that is considered holy, blessed, or revered in a religious or spiritual context. For example, "This temple is a sacred place for worship," or "The sacred text is highly respected by the community."
The jewish book of sacred texts is called the Torah
Many Protestant Christian denominations use the King James Bible as their primary religious text.
The Buddhist use 'sacred texts' or 'scriptures'. But it is nothing like the Bible of Koran (al-Quran, right?). It contains teachings, sayings of the Buddha.
All protestant churches use the Holy Bible as their sacred texts in the same way as the Roiman Catholic Church. The only minor difference is that in the Roman Bible some books are included that are not regarded as worthy of being called 'scripture' in the Protestant Churches. In 'protestant' bibles these books (like the Maccabees, Tobit, baruch etc) are often included in a separate section.
The three Abrahamic religions are Judaism (the Tanakh), Christianity (Old Testament), and Islam (the Taurat).
