The Rev Robert Bradford, United Ulster Unionist Coalition MP for Belfast, South, named the Catholic Church, with Marxism and ecumenism, as the main source of problems in Northern Ireland and the world.
Mr Bradford, a Methodist Minister and former member of the Vanguard Party, first elected to Westminster in February 1974, was speaking at a conference on Ulster and Christian Morality at the ecumenical Corrymeela Centre, Co Antrim.
"I am one of the one to two million who believe that the British people have a particular responsibility in cosmic terms. We are the modern representatives of the Israel people." These representatives would encounter "insidious opposition" which would end their mission and destiny.
"We, in these islands, were kept together as a unit to Christianise the world. The Roman Catholic Church was in conflict with the great evangelical revival of the 18th century in almost every part of the world."
Scripture could be interpreted in the light of current events.
He saw the Marxist threat ending in a "great cataclysmic explosion." He joined the UUUC because it recognised the danger of the Roman system. "If the UK is to survive, then elements whose purpose is to destroy must be dealt with and if that involves killing, then that has got to be," he said.
The EEC was also a threat because it "is an expression of the political involvement of Rome" and part of the conspiracy.
The Irish Foreign Minister, Dr Garret FitzGerald, was present for part of the conference, which heard talks from Mr John Hume, deputy leader of the Social and Democratic Labour Party, and the leaders of the Northern Ireland Labour Party and the Alliance Party.
The conference decided that questions drawn up by the Corrymeela Community with the help of clergy would be put to candidates of all parties in the Constitutional Convention elections, expected to be announced soon. They will ask how much candidates value compromise and to what extent they are motivated by Christian principles.
