His contribution to the Biblical studies

In the field of biblical literature his scholarly speciality was mainly the Sayings of the Historical Jesus, the Q-Document, the Pauline theology, and the theology of Liturgy and Eucharist.
Ηis contribution to the Synoptic scholarship was mainly his widely accepted and used procedural principles for the reconstruction of the Q-Document and the consequences of the Q Hypothesis, not so much as a solution to the Synoptic Problem, but as a change of the conventional picture of Christian origins. With regard to the Pauline collection project, on the basis of a thorough examination of 2 Corinthians 8-9, he is among those specialized scholars who support the social character of this ancient radical institution of Christianity, the main purpose of which was the ideal of “equal distribution and permanent sharing of the material wealth.” As to the Pauline Theology his recommendation is a combination of historical and thematic approach of this discipline, with a parallel recognition and use of such semi- and extra-canonical texts and traditions, as Q and the Gospel of Thomas among others, suggesting what he calls a “Eucharistic Paradigm”.

His theological contribution

Although his primary scholarly profession is biblical, he has deliberately chosen to engage with the wider theological scholarship. With the decline of the word of God, the Gospel and the overall biblical foundation of the Orthodox theology, mainly as a result of the predominance of the institutional expression of the Church at the expense of her charismatic character, he attempted in many of his works a creative encounter between the later development of the ecclesiastical tradition and the modern theological problematic with the foundational biblical tradition. Realizing the fragmentation of contemporary theological scholarship, and wishing to overcome it, he extended his scholarly and practical engagement to other areas, such as ecumenical movement and theology, missiology, liturgical theology, and world theological education.
Among his characteristic theological propositions is the priority of the eschatological experience of the early Christian community over against its literary products, although from the time of St. Paul there has been a shift of the center of gravity from the experience to the message, from eschatology to Christology, from the event, to the bearer and center of this event. This basic theological positions of his, i.e. the priority of the horizontal perspective, both in the N.T. and in the early Church, as well as in later Christian literature, with the vertical soteriological teaching placed always within the framework of the horizontal eschatological as complementary, has determined his extra-biblical theological activity and research.
Basing his theological endeavour on the foundational, yet marginalized, incarnational Christian doctrine, and maintaining the overcoming the traditional patristic “exclusivity” of modern Orthodox theology, and in addition promoting the necessity of the biblical foundation of the Eucharistic ecclesiology, he adamantly promotes – following the legacy of his Doctor Vater, the late Savvas Agouridis – the Prophetic theology, above and beyond the contemporary classical “theologies”, which dominated his country since the decade of the ‘60s, i.e. the Eucharistic and the therapeutic. In quite a number of his works he opined that the relegation of the biblical word has inevitably resulted in limiting contemporary theology in dilemmas of the type: therapeutic or Eucharistic theology, gerontes/starets or bishop, theosis or sacraments etc. Following the general line of Metropolitan of Pergamon, John Eucharistic ecclesiology for the necessity of the “primacy” on a theological and not just historical basis, he also brought into the fore for reconsideration the views expressed by the pioneer in the field Nicholas Afanasiev, underlining Pneumatological and the Missiological dimension of the Church, thus coming closer to the theological views supported by the Archbishop Anastasios of Tirana, Durrës and All Albania.

His missiological contribution

Based on this position and relying on the biblical data he suggested a reconsideration of the Orthodox position on intercommunio and of the exclusivistic character of the Eucharist, as well as of the Orthodox position on Christian anthropology.
From the mid-80s he promotes a new “paradigm” of Christian witness in the post-modern era, being at the same time systematically engaged with the Orthodox understanding of the ecumenical theology, underlining the Christian witness as the real Liturgy after the liturgy and insisting on the necessity of the inter-Christian and inter-faith dialogue, and especially the biblical and liturgical renewal.
During the last decade he is specialized and practically engaged in the alternative Christian proposal. His engagement with the interfaith dialogue, and his position for an encounter between Christianity and modernity made him aware of the need of a legally established and internationally binding Universal Declaration of Human Responsibilities, along with the Human Rights. He suggested that the interfaith dialogue and cooperation are necessary in the areas, where the “modern paradigm” failed to succeed, i.e. in the spiritual and material welfare of the people, the degradation in social and moral values, in the inability of our world order to enforce a lasting just peace on earth, and especially in its unwillingness to preserve the natural environment, and its surrender to the rules of the dominant world economic system.

Contribution to theological education

In 2002, after more than a decade in WOCATI, having also served as member of the executive committee, he was elected WOCATI's president, and for his contribution he was awarded for life the title of its honorary president. His scholarly contribution on the world ecumenical theological education is specified in combining the new challenges with the traditional Christian presuppositions. On the basis of his international experience and the nearly 40 years academic service in Greece he is one of the contributors to the revision of the religious course in the public secondary education of his country, and a fervent supporter of the constitutional changes in Greek public higher education, and a member of the Association of Professors of the Aristotle University of Thessaloniki.
