Quaker Testimonies on the Plain Language Witness
Quaker Spirituality and the Use of Plain Speech
Elizabeth Gurney Fry, Quaker humanitarian (1780-1845)
I used to think and do now how little dress matters. But I find it almost impossible to keep to the principles of Friends without altering my dress and speech. . . . They appear to me a sort of protector to the principles of Christianity in the present state of the world.
(To the Flock of Christ Jesus every where, to be read in their Assemblies)
. . . CHRIST saith, In me ye have Peace, in the World ye have Trouble; and therefore keep out of the Spirit of the World; let not the Spirit of the World come into you; for if ye do, ye go into Trouble both inwardly and outwardly: But if ye keep in Christ, who is not of the World, you keep your heavenly Place and Region; . . . and therefore keep in the Life in Christ. . . .
I am not Amish or Mennonite, but some people who come to my website are interested in knowing more about these groups. I can recommend these books as authoritative and relatively inexpensive sources of further information.
