St. Gregory Nazianzen Orthodox Institute is fully accredited by the Department of Education of the Greek Orthodox Archdiocese of Mexico, Central America, Colombia, Venezuela, and the Islands of the Caribbean (Ecumenical Patriarchate of Constantinople), and is thereby certified to prepare and train candidates for ordination and/or other ministries and leadership roles in the Church. The Institute's Faculty, which has a distinguished international reputation for research and teaching, offers training at an acknowledged world-class standard (see Faculty). Students are trained at the certificate, undergraduate, graduate, and postgraduate level in an atmosphere of rigour, discipline, and strong collegiality. The most distinguishing and remarkable characteristic of the Faculty is the common commitment to transdiciplinarity and unity of knowledge, which includes the emphasis on the integration of Orthodox studies, (and/or theological methods or approaches), with personal spiritual experience and piety, orthopraxis, and moreover, character. This focus is seen as mutually fecund and necessary, and is applied to all the disciplines offered for study. The Faculty offers a broad multidisciplinary spectrum, which promotes and encourages students to pursue transdisciplinary studies and research.
The Institute therefore advances apostolic diakonia and outreach, by creating an environment that fosters growth in knowledge, faith, spiritual life and experience, orthopraxis, and service. The academic offerings at St. Gregory Nazianzen Orthodox Institute are religious in nature, (i.e., they are not primarily directed toward the preparation of students for the general labor force or other secular purposes). The Institute is therefore exempt from state authorization and accepts no governmental grants or financial aid. St. Gregory Nazianzen Orthodox Institute’s headquarters are located at the Archdiocesan Offices in Mexico City; with campuses in San Juan (PR) and Nueva Concepción (GT).
