There is probably no better known name within contemporary Christian music than that of Hillsong. Since 1992 they had released more than forty albums with many of them reaching top positions in both the Christian and mainstream music charts. In twenty years they have sold more than twelve million records around the world and have signed marketing deals with Warner and Sony, bringing Hillsong worldwide popularity and recognition. However Hillsong is not simply a music ministry, but principally a network of large churches, commencing in Sydney Australia were it is pastored by Brian and Bobbie Houston, now with congregations in major cities around the world including London, New York, Kiev and Cape Town. The popularity of Hillsong's music means that many Christians are also attracted to their churches and to the personalities and teachings associated with them, and this is a matter of grave concern. Behind their popular music packed concerts we find such serious issues that we are led to say that Hillsong is not so much a promoter of scriptural truth, but rather of unscriptural heresy.
