Here is the beginning of our list of links. I am beginning this list with explicitly Christian sites and for lack of a better organizing method they are listed by denomination or parachurch organization. At each site there may be other useful links, these are simply places for you to begin.
PC(USA) resources
ELCA; Human Trafficking Awareness Day
Reformed Church in America resources
Christian Reformed Church resources
Evangelical Covenant Church resources
United Methodist Church resources
Vineyard resources
Free Methodist Church resources
Clearly this is not an exhaustive list. Please add your own church’s resources via comments.
