We’re still tracking down the start of SPICE:
If you ask about Quaker beliefs these days, one of the common answers you’ll get is SPICE, a handy acronym that holds together a hodgepodge of values, namely: simplicity, peace, integrity, community and equality (and later sustainability to become SPICES). One Quaker school definitively puts it, “Quakers agree to a core set of values, known as testimonies.” I’ve not found SPICES listed before 2000 and even many of the individual components are absent from older books of Faith and Practice.
