In this Sunday’s study, Mr. Anthony Ally reflects on the teachings of Saint Haralambos and explores why the Orthodox Church does not concelebrate the Eucharist with non-Orthodox Christians. Rooted in love and truth, this episode unpacks the Orthodox understanding of unity—not as mere external agreement, but as full communion in faith, sacraments, and life in Christ. Drawing on patristic witness, Scripture, and the lived Tradition of the Church, we examine how preserving the integrity of the faith is not exclusionary, but a call to authentic oneness in Christ.
