Abstract
The paper analyses, in the light of the recent magisterial documents of the Church, one of the practices present in the life of the Catholic Church, the so-called Family Tree Healing (FTH). The study focuses foremost on the most important source of this practice in the Czech Republic, that is the book Healing Family Tree by Kenneth McAll.
It evaluates its inner reliability and logics, and some problematic points of the theoretical basis of this practice in the context of the Catholic doctrine. The authors find that the FTH contradicts the Catholic doctrine on a biblical basis especially in the question of reduction of the evil and the freedom of man.
In the conclusion, the study proposes a hypothesis that the FTH represents a reaction to the spiritual vacuum experienced by the modern man and that the concepts associated with FTH are not strange to similar phenomena in the current popular culture, but also in the Asian shamanism.
