I would focus on one issue...with you seeking clarity on WTS policies. The issue I'd choose would be blood.
Cofty provided some excellent research on the subject as well as Paul from JWfacts.com
Some of the questions I would ask include:
There
are some things I don't understand about the religion of Jehovah's Witnesses.
Could
you explain why JWs believe blood transfusions are unscriptural?
(Acts15)
a.
Which components of blood are acceptable and which ones are not and
what is the scriptural basis for this distinction?
b.
Why is plasma (55& of blood volume) unacceptable when all of its
elements and fractions are on the WTS acceptable list? Plasma is made
up of 92 % water, albumin and fibrinogen proteins. What's the
problem?
c.
Why are white blood cells banned when 97 percent of the white cells
are not found in the blood stream but in organ tissues that are
permitted (since 1980) by the WTS to transplant? Of course millions are
transferred with every transplant. By the way, 12 times more white
blood cells are found in a mother's milk than in the blood. Millions
are passed from mother to child at every feeding. Seems that Jehovah
doesn't abide by the same rules JWs do.
d.
Why is it sinful to store whole blood? Where is the biblical
exception that allows JWs to have their blood stored in tubes for
lab technicians to test? By the way, only blood of animals that were
slain by Jews under the law was to be poured out. No one was slain
to acquire the blood stored in blood banks.
e.
Why is it alright for JWs to use the life-saving fractions (eg. Factors VIII
and IX) derived from the donated and stored blood of others when
these products are allegedly stored immorally. And aren't hemophiliac
Witnesses leeches when they take these blood products without
contributing to the blood bank themselves?
f.
Where is the rule found that it is OK to remove blood from the body
to be cleaned..as long as there is no interruption in it's flow back
to the body?
g.
Why did it take JWs over 70 years to find these rules out when they
are so obvious to JWs now. And didn't Jesus appoint the F&DS in
1919 when JWs were still being encouraged to work for the Red Cross
as alternative service and give and receive transfusions when
necessary?
Now
regarding the actual eating of blood:
h.
Can anything that goes into the mouth of a Christian defile him?
Ro.14:14
i.
Assuming that there is no one around with a weak conscience, should
Christians ask questions of conscience about meat served in the home
of a pagan idol worshiper who is known to eat things strangled? I
Cor.10:27
j.
Why do you think Jews could eat animals found dead in their fields
(unbled) with relative impunity. They would merely have to wash their
clothes and be unclean until evening.
Levitcus
11:38,39 - "If
an animal that you are allowed to eat dies, anyone who touches its
carcass will be unclean till evening. Anyone who eats some of its
carcass must wash their clothes, and they will be unclean till
evening. Anyone who picks up the carcass must wash their clothes, and
they will be unclean till evening."
k.
Could it be that the dietary laws in Acts 15 were temporary, designed
to help unify Jews and Gentiles. If so the WTS has had
blood on its hands since 1945 and even before with it's outlawing of
vaccinations (30s, 40s & 50s) and later organ transplants (1967 -1980).
Good luck.
