The result of a liberal secularist "no-values" society. If you don't truly have some fixed values based on something higher than yourself, you will fall for anything, like these sects.
Could be, it´s strange really - the pentecostal movement is very strong in rural Sweden and respected (so far). It has a definite flaw though in that it has no central leadership. The national "movement" tried to intervene in this case but all they could do was to remove their right to perform weddings. IMHO not enough in this case.
Where there is a vaccum, the cults rush in. I have never understood the cult mentality, where people are eager to give up their identities and join with other likemindless fools. This "church" sounds absolutely demonic and I bet the media are saying that this cult represents traditional Christianity.
