Eugenics and Roman Catholicism An Encyclical Letter in Context:Casti connubii, December 31, 1930

Abstract

The ArgumentLittle has been written about religion vis à vis eugenics and, even less on Roman Catholicism and eugenics. A 1930 papal encyclical,Casti connubii, is usually held by historians to have been the official condemnatory view of the Catholic Church on eugenics, and the document is further supposed to have induced the only organized opposition to eugenic legislative efforts in several countries (especially France). In fact, the encyclical was not directly about eugenics but a general statement of the Catholic doctrine on marriage.This article attempts to clarify the issue of a Catholic position on eugenics by re-examining the encyclical itself as well as its contemporaneous reception in Germany and France, where there was a strong Catholic presence.Casti connubiiintroduced a change in the prescribed hierarchy of the aims of marriage when, for the first time, relations between spouses took precedence over procreation. While condemning the means (abortion, sterilization, etc.), the encyclical did not condemn positive eugenics. In the broader context of the history of eugenics, the reception of the encyclical emphasizes the family as the third entity between the individual and society. Eugenics, as a “religious Utopia” of modernity, developed a hegemonic discourse over the family realm. As such it entered into competition with more traditional religious institutions such as the Roman Catholic Church.
