On Monday, June 22, 2026, the Universal Peace Federation hosted an interreligious prayer meeting in Düsseldorf. At a time when many people are searching for peace and mutual understanding, the evening centered on the different Christian traditions and their shared roots. The event was moderated by Anja Brina, who welcomed the guests and guided them through the program.
The focal point of the gathering was a lecture by Archbishop Gino Collica of the Catholic Apostolic Church Europe. He spoke about the Catholic and Orthodox doctrines, highlighting both their similarities and differences, as well as paths toward greater mutual understanding. Archbishop Collica offered an overview of the shared origins of the Christian churches and recalled Antioch, where, according to the Acts of the Apostles, the disciples were first called “Christians.” From this common root, the various traditions later developed.
Another important focus was early Church history. Archbishop Collica explained the role of Emperor Constantine, who sought a united Church for political reasons, in order to stabilize the Roman Empire. At the same time, he showed how theological conflicts emerged at an early stage. Among them was Arianism, which questioned the equality of Jesus Christ with God the Father and ultimately led to the First Council of Nicaea.
Archbishop Collica explained the dispute over the “Filioque” with particular clarity—the addition to the Creed stating that the Holy Spirit proceeds “from the Father and the Son.” Over the centuries, differing views on this issue created tensions and ultimately contributed to the split between the Western and Eastern Churches in 1054. He emphasized that the division was shaped not only by matters of faith, but also by cultural differences, political interests, and misunderstandings. In this context, he stressed that the Church of Jesus Christ is one in its origin and that, despite the existence of different traditions, Christians are called to encounter one another with respect, love, and openness.
Following the lecture, the participants joined in a prayer for peace, Christian unity, and the brotherhood and sisterhood of all people. For many, this moment of silence and shared prayer was deeply moving.
At the close of the evening, UPF invited everyone to enjoy drinks and light refreshments. Many guests used the opportunity to continue the conversation, explore questions in greater depth, and make new contacts. Sincere thanks were extended to Archbishop Gino Collica for his insights and to all the guests who contributed to this evening of dialogue and hope.
