Estudios Trinitarios is the scientific journal of Trinitarian theology published by Editorial Secretariado Trinitario of the Province of the Holy Spirit (Spain) of the Order of the Most Holy Trinity and of the Captives. Since its first appearance in 1967, Estudios Trinitarios has made a significant and widely recognized contribution to the development of Trinitarian theology through the writings of its many contributors. Its relevance within the field of theology has fostered dialogue with the major areas of human knowledge (biblical studies, dogmatic theology, moral theology, practical theology, philosophy, anthropology, history, art, education, etc.).
