USUALLY Quakerism started as a Christian denomination. The name “Religious Society of Friends” comes from Jesus saying to the Apostles “I have called you friends” (John 15:15). Most Quakers around the world are Christian, and most would tell you that Jesus is the Word (John 1:14). Conservative Friends would say that they are “Christ-centric”.
There is, however, a subset of Liberal Friends who regard Jesus as an enlightened teacher whose example should be followed rather than a saviour or deity.
Depending on whether you define a Christian as someone who believes in atonement through Jesus’ death or as someone who follows Jesus’ teachings, varying numbers of Quakers would meet your definition.
