Individuals, groups, churches and councils of churches from Kenya to Sweden to the United States to Australia are carrying out hundreds of advocacy actions involving Christians concerned about the Gaza crisis, especially the collective punishment of the people of Gaza, and the need for a just and lasting peace between the Israeli and Palestinian peoples.

The WCC has received reports of church-related advocacy in some 30 countries, including meetings with governments, letter campaigns addressed to government officials and parliament members, public statements and demonstrations. They are usually accompanied by vigils and prayer services and collection of funds to support humanitarian relief work.
A sample of those actions is listed below. Their goals include an immediate ceasefire that ends violence against civilians on both sides of the border, free access for humanitarian aid, lifting of the blockade on Gaza, and internationally sponsored negotiations under the framework of international law as the basis for peace.
