The concepts of trinity and ternarity are fundamental to think about the inter-religious dialogue. The relational expression of the trinity appears in the Nicene Creed s third article (381 A.D.). In spite of that, the Holy Spirit remained in theology for centuries, because of the binitary base in the western thought s logic. This fact generated a false polarization between faith and science, and monoteism and pluralism. When the ternarity was revealed for the Peirce s philosophy (19th century) and the Planck s quantum physics (20th century), it became the category of the transdisciplinarity. Theology continued working by the Aristotelian paradigm - binitary, misogynistic and with the potency in the visible thing - and producing erudite monological speeches, self defensives and solitarians, in a counter-attack that provoked arrears in the theological-philosophical reflection of the western world, with impact in the ecumenical and interreligious relationships. The new theological paradigm questions theologians about their responsibility in front of the community, because they touch life ethics and imply salvation. Its incidence in Latin America is important because the historic confrontation, military dominance, cultural submission and religious imposition of her. Under the influence of the liberation, feminist, black and indigenous theologies, the eclesialities are called to review its relationship with the postmodernity, minimum base to enter in the inter-religious dialogue. And reconstruct new epistemological bases to think the trans-religious, without succumbing to the monoteist temptation of constraining the reality to according with our purpose.
