This essay tries to show the diverse ways in which it is possible to refer to the Christian Trinity inside the Latin American culture. An example is given—the Mexican culture—where Christian beliefs are continuously changing under the impact of certain ideas and practices from the postmodern mind. Contemporary Latin American cultures are a mixture of pre-modern, modern, and post-modern elements. The belief in the Trinity is a product of these elements and expresses social, political, and ideological transformations. The traditional, dogmatic, Christian teaching of the Trinity is not the main source for comprehension in that situation. Indeed, theological education has not brought enough explanation of the better form to actualize these types of beliefs. Both Catholic and Protestant theologies need a fresh approach to this problem.
