When the doctor, Titius, was called to a pregnant woman who was seriously sick, he gradually realized that the cause of the deadly sickness was nothing else than pregnancy, that is, the presence of the fetus in the womb. Therefore, to save the mother from certain and imminent death one way presented itself to him, that of procuring an abortion, or ejection of the fetus. In the customary manner he adopted this way, but the means and operations applied did not tend to the killing of the fetus in the mother's womb, but only to its being brought forth to light alive, if it could possibly be done, although it would die soon, inasmuch as it was not mature.Yet, despite what the Holy See wrote on August 19th, 1889, in answer to the Archbishop of Cambrésis, that it could not be taught safely that any operation causing the death of the fetus directly, even if this was necessary to save the mother, was licit, the doubting Titius clung to the licitness of surgical operations by which he not rarely procured the abortion, and thus saved pregnant women who were seriously sick.
Therefore, to put his conscience at rest Titius suppliantly asks: Whether he can safely repeat the above mentioned operations under the reoccuring circumstances.
The reply is:
In the negative, according to other decrees, namely, of the 28th day of May, 1884, and of 19th day of August, 1889.
But on the following Thursday, on the 25th day of July . . . our most holy Lord approved a resolution of the Most Eminent Fathers, as reported to him. (Reply of the Holy Office to the Archbishop of Cambrésis, July 24, 25, 1895)
It may be a serious question of health, sometimes of life or death, for the mother; it may be the burden represented by an additional child, especially if there are good reasons to fear that the child will be abnormal or retarded; it may be the importance attributed in different classes of society to considerations of honor or dishonor, of loss of social standing, and so forth. We proclaim only that none of these reasons can ever objectively confer the right to dispose of another's life, even when that life is only beginning. (Sacred Congregation for the Doctrine of the Faith, Declaration on procured abortion §14)
Nobody is asking anyone to sacrifice themselves. The Church is aksing people not to commit murder.
