In my reading of Eusebius regarding Biblis (Biblias), I would now just like to add my humble 2 cents worth for what it is worth.
The WTS (in the above quote from its blood booklet) suggests that a women died for her principles on not eating blood. Here lies the first problem with the WTS quote. The WTS doesn't tell us who the women is. Thanks to some person with years more experience than me I was able to post the above and we are now able to find out that this women is Biblis.
It is true that Biblis did utter a phrase "...are not allowed to eat the blood even of irrational animals" according to the writings of Eusebius. But the WT conveniently forgets to add the first part of the sentence that Eusebius used.
If you read Book 5 of Eusebius (which I have quoted for you in the above posts), Eusebius lists all the stories of people who were put on the "rack" by the pagans and killed for being Christian or supporting the Christians in the area of Lyons. One of the persons who was put on the rack by the pagans was a lady named Biblis (or Biblias). Biblis was put on "rack" with the thought that the she would expose the Christians as people who eat children. The feeling among the pagans was she would expose the Christians as the eaters of children because she didn't believe in Christ. Of course, while on the "rack" and while being tortured, Biblis came to her senses and found Christianity. At this point she refuted the pagans who were torturing her and supported the Christians. Eusebius states "How, she said, could those eat children who do not think it lawful to taste the blood even of irrational animals?'"
Biblis point was Christians don't partake in eating children. She tells the pagans, how could Christians be eating people when don't taste the blood of irrational animals. The point she was making is eating blood and flesh are cannibalistic acts. Christians don't practice cannibalism or murder.
Biblis was talking about the gross sin of cannibalism (eating children) and nothing more. She did not want to compromise the principle that Christians did not partake in eating children and that is why she died on the rack. She did not die on the rack because of some dietary blood prohibition.
The WTS tries to portray the story of Biblis as someone who died for the principles of not eating the blood of irrational animals. The WTS even knew the name of the women but didn't put it in their blood brochure. Why? Because any Witness could look up Biblis in their own WT publication "Insight into the Scriptures" and there, using the WTS own words they could link Biblis to the principle of how Christians didn't believe in cannibalism and not a dietary blood ban.
Just a couple of thoughts.
