Scottish Churches Housing Action, which brings together 13 Christian denominations and organisations nationwide, with a commitment to ending homelessness, will be 20 years old this month. The precise anniversary is 17 January 2015 and it will be marked with a service of celebration, challenge and commitment at St Andrew's Roman Catholic Cathedral, Clyde St, in Glasgow at 2.30 pm. Worship will be led by the Scottish Churches Housing Action associate convener, the Rt Rev Bruce Cameron, and the sermon will be given by Very Rev Dr Andrew McLellan from the Church of Scotland. Scottish Churches Housing Action has a substantial track record in developing local volunteer-based initiatives such as its recent befriending initiatives for homeless people. It encourages the development of affordable housing from redundant or under-used church property. The group also works to increase church and public understanding of homelessness and policies that will end it.
