Interesting to find that 2 Catholic priest’s, one a jesuit, are the fathers of modern hypnotism.
“The Church has not waited for the verdict of science to put the faithful on their guard against the dangers of magnetism and hypnotism, and to defend the rights of human conscience; but, ever prudent, she has condemned only abuses, leaving the way free for scientific research. “The use of magnetism, that is to say, the mere act of employing physical means otherwise permissible, is not morally forbidden, provided that it does not tend to an illicit end or one which may be in any manner evil” (Response of the Holy Office, 2 June, 1840). The encyclical letter of the Sacred Penitentiary, Tribunal of August, 1856, only confirms this, and Père Coconnier has referred to it in his famous work “L’Hypnotisme franc”, in which he studies the subject apart from all extraneous considerations. Taking up the latest teachings of Rome, Canon Moureau, of Lille, writes: “Hypnotism is tolerated, in theory and in practice,
to the exclusion of phenomena which would certainly be preternatural.” This is the opinion of most theologians, and it is the utterance of reason.”
