The Quakers use the standard Christian bible, in whatever translation they individually prefer. Well over a century ago there were individual Quakers on the founding board of the American Bible Society.
The Quakers are Christians, and they believe in the Bible.
by reading the bible
Quakers and Puritans both sort of tried to model themselves like Jesus and follow the Bible every day. Puritans and Quakers both agreed on the central role of the Bible and on the importance of a disciplined life.
Being brought up in a Quaker family I feel that Quakers do not doubt that the Bible was divinely inspired. Most Quakers felt and feel that the Bible is a holy book that should be read to further your knowledge of a related religion. But, and this is a point that is commonly confused with the root of your question, most Quakers do not believe the words and how the Catholic church proclaims that they are true. This is often confused with not believing in the divinity of the Bible. I hope this helps answer your question and I thank you for taking an interest in a topic such as this.
The founder of the Shakers, as a religious group, was formerly a Quaker. Both Quakers and Shakers use the Bible as their fundamental religious book.
Baptism - Most Quakers believe that how a person lives their life is a sacrament, and that formal observances are not necessary. Quakers hold that baptism is an inward, not outward, act. Bible - Quakers' beliefs stress individual revelation, but the Bible is truth. All personal light must be held up to the Bible for confirmation. The Holy Spirit, who inspired the Bible, does not contradict Himself.
The Quakers believe in pacifism and nonviolence as core principles of their faith. Some Quakers actively engage in social justice and community service work as a way to live out their values. We met a group of Quakers at a peaceful protest advocating for environmental conservation.
no they don't Amish don't either
Gurus don't use a Bible.
Quakers are a largely liberal denomination, and although not all Quakers are of one mind about this (there is division over this issue), generally speaking Quakers are one of the most LGBT-accepting of the older Christian denominations out there. On the east coast, Quakers tend to be less structured, often somewhat less strictly Bible/Christianity-centric and more liberal and accepting of gays, but in other parts of America, Quakerism takes on a more structured form and may be less accepting of LGBT folk.

Only the Pharoah quail (coturnix coturnix) is kosher but it's very very difficult to slaughter them properly for kosher use.
