Do these ladies know that you were one of Jehovah’s Witnesses?
If not I would ask them why Jehovah’s Witnesses are against blood transfusions.
Watchtower Society (WTS) Blood Policies
NOTE: JWs will always try to divert the topic to say there are wonderful non-blood alternative procedures that can be used instead of blood. My suggestion is that you say you just want to look at what the scriptures say about blood transfusions as wonderful as some of the non-blood procedures may be. Yes, avoid transfusions if possible (i.e. when there is not massive blood loss) but the question you are asking is why do Jehovah's Witnesses say the Bible is against transfusions.
There are some things I don't understand about your religion:
1a. Could you explain why JWs believe blood transfusions are unscriptural? (Acts15:29)
1b. Does Acts 15 mention blood transfusions? (It's implied) Is it implied or are you extrapolating? (Abstain means to abstain!)
1c. Is it possible that the three dietary restrictions in Acts 15 were temporary; to avoid offending Jewish Christians? Note: regarding food offered to idols: In 1Cor 8 Paul explains clearly that a brother who eats food sacrificed to idols commits no sin except if he risks stumbling his brother.
1d. Why do you think Orthodox Jews have no problem with blood transfusions?
1e. Do you think a doctor would be upset if he told a patient to abstain from alcohol – but found out he was using rubbing alcohol on his skin? (objection external vs internal)
1f. OK would a doctor who told a patient to abstain from meat be upset if the patient later had an liver transplant? (???) Note: A blood transfusion is actually an organ transplant.
2a. Would a blood transfusion be acceptable to Witnesses if it was their own blood that was stored for transfusion? (No!) Why not? (it's sinful to store blood; it must be poured out)
Note: This OT rule was for animals the Jews killed themselves to show respect for the life taken. No one was killed to obtain blood for transfusion.
2b. Are JWs permitted to have blood tests? If it is sinful to store blood, where is the biblical exception that allows JWs to have their blood stored in tubes for lab technicians to test? (only temporarily stored)
2c. Are JWs permitted to have dialysis? The blood must leave the body to be cleaned, so shouldn't that blood be poured out? (Dialysis is OK because the blood is in a continuous flow back to the body) 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?
2d. Is it permitted for hemophiliac JWs to use blood clotting fractions VIII and IX which are derived from the donated blood of others? Is it alright to profit from the sinful actions of others? Let's say a group held a strip-a-thon to gain money for the WTS, could Jehovah's Witnesses accept that money in good conscience? (No) So why is it OK to accept products from immorally stored blood? Also aren't Witnesses leeches when they take these blood products without contributing to the blood bank themselves?
3a. Which components of blood are acceptable to Jehovah and which ones are not? (the 4 major components disallowed are red blood cells, white blood cells, platelets and plasma) What is the scriptural basis for this distinction?
3b. Why is plasma (55% of blood volume) unacceptable when all elements and fractions in plasma are on the WTS acceptable list? Plasma is made up of 92 % water, plus albumin and fibrinogens and other proteins. So what's the problem? If plasma is made up of entirely acceptable elements – why ban it's use. It's like saying you can eat cheese, bread, lettuce and mayo separately, but you can't eat a cheese sandwich.
3c. 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 by the WTS to transplant? Note: billions of white blood cells are transferred with every major organ transplant.
3d. Why are white blood cells banned when 12 times more white blood cells are found in a mother's milk than in the blood stream? Millions are passed from mother to child at every feeding? Seems that Jehovah doesn't abide by the same rules JWs do.
3e. Do you believe blood is always sacred to God? (Yes) If a Jew had bled some blood from an animal without killing the animal, would the extracted blood have been acceptable as a sacred sacrifice to God? (blood is sacred because it symbolizes life) Is a symbol of life (blood) more valuable than the life that it symbolizes?
4a. Now regarding the actual eating of blood: Can anything that goes into the mouth of a Christian defile him? Ro.14:14 (???)
4b.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
4c. 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." (see also Leviticus 17:15)
Note: It took JWs over 70 years (right up to 1945) to find these rules restricting blood use when they are so obvious to JWs now. It's interesting that Jesus appointed 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?
