The elements of this already-given Church exist, found in their fullness in the Catholic Church and, without this fullness, in the other Communities,20 where certain features of the Christian mystery have at times been more effectively emphasized. Ecumenism is directed precisely to making the partial communion existing between Christians grow towards full communion in truth and charity_.In a corresponding way, there is an increased sense of the need for repentance: an awareness of certain exclusions which seriously harm fraternal charity, of certain refusals to forgive, of a certain pride, of an unevangelical insistence on condemning the "other side", of a disdain born of an unhealthy presumption. Thus, the entire life of Christians is marked by a concern for ecumenism; and they are called to let themselves be shaped, as it were, by that concern. (Papal Encyclical, Ut Unum Sint, 25 May 1995).
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
