Modrý kríž (Slovak for Blue Cross) was a "teetotalers' society" originating in Stará Turá, Slovakia at the end of the 19th century and the beginning of the 20th.
The society encouraged its members to become born-again Christians by means of everyday prayers and Bible study, while forbidding the consumption of alcohol, smoking, playing cards and dice, blasphemous speech, and obsessions of a sexual or other kind.
Society helps its members to interrupt their unhealthy lifestyle with alcohol, passion for money and sexual enjoyment.
On the other hand, they act as sect in various ways, for example explain bible without sufficient knowledge according to rules in society and manage the lives of the members with massive manipulation similar to Charismatic movement.
[3] Modrý kríž can be a benefit for an addicted person, but also dangerous in a negative psychological effect of inadequate controversial "sectarian" denomination practices on critical perception of reality and spiritual life of a member.
