During the late 1960s the UNIP government embarked on a more radical socialist agenda which became known as Scientific Socialism. This move alarmed the wider Christian community of Zambia fearing that it could lead to Marxist Humanism in the nation. The ECZ, CCZ and EFZ took the unusual step of issuing "a joint statement entitled Marxism, Humanism and Christianity". The government fearing a backlash from the public toned down its policies. Phiri comments on this episode, "the churches discerned that the UNIP was adopting socialism not necessarily because of an ideological change of heart, but as another method of control." The success of the combined pressure prompted the three bodies to continue to work closely in terms of public policy, which Gifford goes on to note "makes Zambian Christianity… virtually unique on the continent" in that "the co-operation includes Pentecostals."
