It is interesting to note that the example of the pregnant woman is inconsistent with the fourth principle of the CCP of continuity. The mother-fetus system is indeed continuous, the interaction between the mother and the fetus is constant, uninterrupted, there is no need to consider any artificial tubes as "part of her body" – they simply do not exist, there is no need to consider everything that the mother gives to the fetus as "still her own" – it is already her own. Thus, immunoglobulins and other substances enter the fetal body continuously. On the contrary, in order for a Jehovah's Witness to be injected with immunoglobulin, it is necessary to collect blood, store it, process it, and store the drug – all discrete actions, which, even with a great stretch, cannot be called continuous or with small delays.

We have already seen how the OSB uses scientific data as arguments (the example of a pregnant woman), when it is not possible to find grounds from the Bible, but something is very much wanted to be resolved. Let's take a small example: "Studies have shown that blood taken from the body cavity remains sterile for 6 hours" [67]. Why don't Jehovah's Witnesses use this scientific fact to allow the short-term storage of their own blood? Then many questions of the applicability of blood-saving drugs would be removed.

In fact, the logical intricacies of the anonymous authors of the OSB are visible. The purpose of reasoning with a pregnant woman is to show the following line of reasoning. God, having created the mother and fetus in such a way that some of the components of their blood could be exchanged, could not have violated His prohibition against the use of blood. If during pregnancy there is an exchange of elements of the blood of the mother and child (namely, God arranged the mother's womb and the process of intrauterine development in this way), then, the Jehovah's Witnesses conclude, God does not object to the use of these components.

What can be answered to this cunning logic? The answer is quite simple and lies on the surface. If Jehovah's Witnesses want to use blood components, but they reject donation, reject blood storage, and care about reverence for the holy object of blood, but allow organ donation,55 then they should use this donor material to obtain these components. Where did they substantiate on the basis of the Bible in their publications, in which they allowed the use of "small fractions of blood", the permission to use donor blood as a raw material for obtaining blood components, which, according to their ideas, should be "poured out on the ground like water"?

In my opinion, the reasoning of Jehovah's Witnesses completely loses all meaning when the following facts become known.

It is well known that a person is quite likely to have twins.56 Although scientists cannot answer with complete certainty what the reason for the birth of twins is, it is unlikely that the event of the birth of twins can be attributed to unnatural or unusual for humans.

It is well known that twins are of two types. Dizygotic (dizygotic, non-identical) twins develop from two simultaneously fertilized eggs. Monozygotic (identical, identical) twins arise when one zygote separates at an early stage of development. The following schemes of fetal membranes in twins are possible:

1. monozygotic or dizygotic twins with separate amnions57, chorions58 and placentas;

2. monozygotic or dizygotic twins with separate amniions and chorions, but with a common placenta;

3. monozygotic twins with separate amnions, but with a common chorion and a common placenta;

4. Monozygotic twins with a common amnion, chorion, and placenta.

In the figure: 1 - each fetus has its own amniotic sac and its own placenta; 2 - both babies share the placenta, but each has its own amniotic sac; 3 - both have one common amniotic sac, but they are separated by fetal membranes, both placentas have fused; 4 - both fetuses have one common amniotic sac and one common placenta.
