All five of Scotland's main political parties have also signed up to a campaign by the Poverty Alliance, which aims to end the use of language that can "reinforce negative stereotypes" about the problem.
The Stick Your Labels initiative, which has been backed by more than 25 organisations across Scotland including councils and voluntary sector bodies, also commits organisations to set out what they will do to help tackle poverty.
SNP leader Nicola Sturgeon, Labour's Kezia Dugdale, Ruth Davidson of the Scottish Conservatives, Liberal Democrat leader Willie Rennie and Scottish Green Party co-convener Patrick Harvie have now given the campaign their backing.
Rev Sally Foster-Fulton, Convener of the Church of Scotland's Church and Society Council said: "Inequality robs us of our empathy, creates a chasm that keeps us from each other.
"From that place of ignorance, about what poverty looks and feels like, about the barriers it builds between a person and the resources and opportunities that enable them to flourish, we who have more than we need cannot see that we are part of the structural injustice that keeps people poor.
"Rather than respond, we resort to hateful and profoundly unhelpful rhetoric."
