Friends' beliefs are a little hard to quantify, since Friends
do not believe in having a fixed Creed or Dogma, but rather
in seeking for the leadings of God within ourselves. However,
some generalizations are possible, which are gone over below.
It is interesting to note that many of these positions have
evolved over time, and while they now seem like fairly
straightforward extensions of basic Quaker belief, they
involved much discussion and soul-searching in the past.
Some issues are still evolving, and you will find that current
issues like same-gender relationships, abortion, etc. are topics
on which it is very difficult to achieve unity. At present, I
suspect you can find Friends Meetings with nearly any viewpoint
in the spectrum of possibilities on these issues, and that any
official position is very carefully worded.
