Petros B. Vassiliadis (Greek: Πέτρος Βασιλειάδης; born 1945) is a Greek biblical scholar and Professor Emeritus of the Department of Theology of the Aristotle University of Thessaloniki (AUTh), honorary president of the Center of Ecumenical, Missiological and Environmental Studies “Metropolitan Panteleimon Papageorgiou” (CEMES) and the World Conference of Associations and Theological Institutions and Educators (WOCATI).

Petros Vassiliadis started his academic career by serving as an assistant to the late professor Savvas Agouridis (1974-1977) at the Theological School of the University of Athens.

Vassiliadis supervised more than 17 master and 10 doctoral dissertations (promoting, in addition to the traditional, the sociological, feminist and other contemporary exegetical methods of biblical analysis), but also of missiological, ecumenical and liturgical character.

In addition, he served in various Synodical Committees of the Church of Greece (of Liturgical Renewal, and of Inter-Orthodox and Inter-Christian Relations), consultant of the United Bible Societies for the improvement of the relations with the Orthodox Churches and the presentation of the Orthodox understanding of the Bible to the global family of the Bible Societies, institutional coordinator of the Forum Mediterraneum, dealing with issues pertinent to faith, history of religions, and cultural anthropological research on the three monotheistic religions of the Mediterranean sea, and member of the editorial committee of the Orthodox biblical journal Δελτίο Βιβλικών Μελετών (Bulletin of Biblical Studies) of the “Artos Zoes” foundation, and of the Regnum Edinburgh 2010 Mission Series of the Oxford Center of Mission Studies.

He published, edited in Greek and English nearly 20 books, and 300 articles in scientific journals, conference proceedings, and collective volumes, as well as in the conventional and electronic press.

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 (and general New Testament) 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”.

Following the general line of Metropolitan of Pergamon, John (Zizioulas’) 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,[17] underlining Pneumatological (in addition to the Christological) and the Missiological (beyond the Eucharistic) dimension of the Church, thus coming closer to the theological views supported by the Archbishop Anastasios (Yannoulatos) of Tirana, Durrës and All Albania.

[23] During the last decade (since 2006, as a member of the WCC program on Poverty-Wealth-Ecology [PWE]) he is specialized and practically engaged in the alternative (to the neo-liberal economic globalization) Christian proposal.

[25] His most influential books are: Professor Vassiliadis has been member of the translation committee of the Modern Greek Bible Η Αγία Γραφή, Μετάφραση από τα Πρωτότυπα Κείμενα, 1989.
