What are some tenets of the quaker religion?

They are a Christian Domination and therefore believe in the basic ideals of Christianity however:

Unlike other Christian denominations, some forms of Quakerism completely reject all forms of religious symbolism and outward sacraments, such as baptism or celebrating the Eucharist. Quakers also believe in continuing revelation, with the idea that God speaks directly to any person, without the need for any human intermediary. For this reason, many reject the idea of priests or holy people, but believe in the priesthood of all believers, and reject the doctrine of sola scriptura. The idea of the Inner Light, or Inward Light of Christ is important to many Quakers: the idea that there is that of God within everyone, guiding them through their lives.
