Abstract
The Catholic movement Communion and Liberation is characterized by a determination to be represented in contemporary society which leads to major economic involvement. Religious belonging is not just a reference point orientating individual values, but above all represents their impetus towards a new life, productive of economic and social works. This perspective impels this group to an economic activism which exceeds the need for simple self-financing. This approach brings a rationalization of volunteerism to the fore, as well as a valorization of members' professional competence. This activism is not achieved without compromise with the political system. In fact, the latter profits greatly from its controlling power over public financing for new businesses, cultural associations and non-governmental associations in order to reinforce its electoral consensus. For this reason, analysis of the rapport between economy and religion leads us, in the case of the Communion and Liberation movement, to the heart of the conflictual rapport between the evangelization of souls and the power of political institutions.
