Quakers are anti-trinitarian and therefore a sect outside of the Church. That is, anyone who denies that Jesus is God in flesh is speaking against God's Word. Now there are many bodies that come out of the Quakers who do believe in the Trinity, but they are marked by inherited anti-trinitarian ideas, confused doctrine and emotionalism. Put simply, any religious body that denies that Jesus is God is not Christian.
God's word explains that the Bible is not required reading.
