More than 500 members of the four churches have signed a petition organised by Normanton Methodist Church's Wayne Grewcock and Normanton's prospective parliamentary candidate for Labour, Ed Balls.
The Rev Grewcock said: "When I saw the overwhelming public response to the tsunami I realised local people felt passionate about international issues.
"That started me thinking about working in the community to support the Make Poverty History campaign, which was launched on TheVicar Of Dibley at Christmas.
Mr Balls supported the Rev Grewcock's ideas, and helped him prepare the petition. The pair are now planning to organise a public meeting before the G8 summit in July, involving congregations from churches across the Wakefield district, and with a high-profile guest speaker.
Rev Grewcock added: "This year is the perfect time to make things happen. We hope pressure will encourage our government to make a commitment to helping struggling countries."
This year sees Britain chairing the G8 summit in Edinburgh. G8 is made up of the world's leading industrial democracies, and meets annually to discuss major economic issues.
This year is also the 20th anniversary of Band Aid, and Britain will also be holding the chair of the European Union during the second half of 2005.
Make Poverty History brings together more than 100 charities campaigning for governnments to help put an end to extreme poverty.
It is also demanding fairer trade, more and better aid and dropping poverty-stricken countries' debts to richer countries, and is encouraging communities to speak out over the issue of poverty.
A spokesman said: "In July of this year, eight world leaders will have it in their power to create the changes, which will make poverty history. But they will only use that power if enough people tell them to."
That is a thought shared by Mr Balls, who during his time as chief economic adviser to the treasury saw poverty in Africa and Asia first hand.
He said: "Witnessing the scale of the poverty experienced in those continents really made me realise how important sustained donations of big money from governments really are.
"Charity is fantastic and changes lots of things, but goals such as reducing poverty by half by 2015 can only be achieved by stable, predictable, long-term funds being delivered to poverty-stricken countries.
"I also know from my experience at the treasury that the government can be persuaded to act quickly if enough people campaign and tell them they want decisive action, which is where the Churches Together petition comes in.
"Cross political grass roots campaigns like Rev Grewcock's really do make a difference to the lives of millions of people."
