Short essay about the primacy in the church

The intent of this short book is to exclude all forms of ecumenical and interreligious dialogue that is not based on the uniqueness of Jesus Christ and on the truth of the Word in the Old and the New Testament.
Starting from the observation that the word of God is truth and it is the only truth, eternal, incarnating 2000 years ago, it is immutable, irrevocable and absolute. First it was entrusted to the Jewish people and then to the church to be transmitted and preserved. It will never adapt to any form of dialogue between religions that do not have this principle of truth only in Jesus Christ.
But before tackling a dialogue with other religions aimed at knowledge of the Word made flesh, the Christian churches must seek ways to unite in their diversity. It would be appropriate to adopt a form of "integration" between:
a. the vision of the primacy of honor and partially legal (in one case) of the bishop of Rome that would save the doctrine of Vatican Council I
b. and the more modern vision of a collegiate primacy (on the model of the twelve apostles) entrusted to the Bishop of Rome and to the primates of the various non roman churches which will protect the deposit of faith from possibly heretical or non biblical positions of the Bishop of Rome.
