Advancing Ecumenical Scholarship & Christian Unity
The Likoudis Legacy Foundation is a 501(c)(3) research institute founded in 2023 to advance Catholic-Orthodox ecumenism, interreligious dialogue, and Catholic formation — and to carry forward the intellectual legacy of James Likoudis, one of the most consequential American Catholic lay theologians of the twentieth century. We operate through scholarship, publication, education, and direct service to dioceses and the wider Church.
Likoudis devoted more than seventy years to a single, coherent project: the reunion of the Eastern Orthodox and Catholic Churches. He argued, documented, and testified to the possibility of that reunion — through books, essays, lectures, and decades of correspondence with Orthodox clergy and scholars. His work helped define what serious ecumenism looked like at the level of the laity.
The Foundation carries that project forward through scholarship, publication, education, and institutional bridge-building. We are directed by Andrew Likoudis, James's grandson, and governed by a board of theologians, academics, and Catholic intellectuals committed to the magisterial center.
I.
Starting from the Church's own center — inter-Catholic unity and the defense of the magisterial center are the precondition for credible ecumenism. From there: Catholic-Orthodox reunion, the primary focus James Likoudis gave his life to; then the wider interreligious dialogue Vatican II opened. Programs: Orientale Lumen conference, Kydones Review, Eastern Catholic canonical clarity initiative, Cornelius à Lapide translation project.
II.
The Church has spoken clearly on the death penalty, immigration, labor, and the dignity of every person. Catholics on both sides of the political aisle find reasons to resist that teaching when it is inconvenient. The Foundation supports the scholarship and formation needed to receive the full social magisterium — not advocacy, but honest reception. Programs: Fellows Program, research publications, consulting, Faith in Crisis chapbook.
III.
Serious theological and pastoral formation belongs to the whole Church, not only to the ordained. The Foundation serves both the pew and the chancery: lay formation through the LLF Reading Circle, Tradition & Renewal Substack, Unmoored Generation initiative, and Koinonia; and direct service to dioceses through canonical clarity resources, consulting, and conference programming. Programs: LLF Reading Circle, Unmoored Generation, Koinonia, T&R Substack, diocesan resources.
James Likoudis was born in 1928 in Lackawanna, New York, to a Greek Orthodox family. He converted to Catholicism in 1952 and spent the next seven decades pursuing a single conviction: that the reunion of Eastern and Western Christendom was not merely possible, but necessary — and that it demanded honest, patient, patristically grounded argument rather than diplomatic vagueness.
He wrote more than ten books and over 300 scholarly essays, was awarded an honorary doctorate of divinity from Sacred Heart Major Seminary in 2020, and drew the recognition of Catholic and Orthodox leaders alike — from Cardinal Burke to members of the Ecumenical Patriarchate — through decades of sustained ecumenical engagement.
He died in September 2024, having been married to his wife Ruth for 71 years. He was 95.
The Foundation operates across publication, education, translation, and institutional dialogue — each program rooted in the same conviction that drove James Likoudis: that good scholarship serves the Church.
A peer-reviewed academic journal of Catholic theology, ecumenism, and patristics — named for the Byzantine theologian Demetrios Kydones, who spent his life laboring for East-West reunion. Volume I is expected in 2026.

James Likoudis was endorsed by figures including Raymond Cardinal Burke, the late Alice von Hildebrand, and Dr. Scott Hahn. His books are held in the collections of Oxford, Harvard, Princeton, the British Library, the Library of Congress, and dozens of Catholic seminaries worldwide.
The Foundation's board and advisory council include leading scholars in dogmatic theology, philosophy, and Catholic social science — drawn from Sacred Heart Major Seminary, Franciscan University of Steubenville, and beyond.
James Likoudis spent seventy years making the case that Catholic intellectual life is worth defending — in print, in correspondence, in town halls, and before cameras. The Foundation exists to carry that work forward. Your gift supports the translation, publication, and distribution of his writings, and the formation of the scholars who will build on them.
