Co-belligerence, strictly speaking, is waging a war in cooperation with another against a common enemy without a formal alliance. The term co-belligerence indicates remoteness and differences between the co-belligerent parties although jointly pursuing a common objective. In Christianity, it refers to an alliance between denominations, which are normally opposed on doctrinal grounds, for a common social goal.
According to one author, it can be defined as a cultural philosophy that warrants questionable alliances in order to make social impact and change against the moral slippage that plagues our nation -- these alliances created and fostered "on the basis of one thing and one thing only the cause at hand."^^ A case in point would be conservative evangelicals allying with the Roman Catholic Church in joint efforts to oppose abortion.
