CHASTE is an ecumenically based charity, which is connected through the Churches Together in Britain and Ireland and the Churches Together in England with over fifty different denominations within the United Kingdom alone.

In Europe CHASTE has been developing its own European network of European Churches responding to the increasing trade in sexploitative labour. Alongside this there is network co-ordinated through the Churches Commission on Migration in Europe of an EU funded project connecting churches and church agencies involved in anti trafficking initiatives and survivor support.
