Dominus Iesus
Dominus Iesus (English: The Lord Jesus) is a declaration by the Congregation for the Doctrine of the Faith (known as "The Holy Office" and formerly, the Inquisition), approved in a Plenary meeting of the Congregation and signed by its then Prefect, Cardinal Joseph Ratzinger, later Pope Benedict XVI, and of its then Secretary, Archbishop Tarcisio Bertone, later Cardinal Secretary of State. The declaration was approved by Pope John Paul II and was published on August 6, 2000. It is subtitled "On the Unicity and Salvific Universality of Jesus Christ and the Church". It is most widely known for its elaboration of the Catholic dogma that the Catholic Church is the sole true Church of Christ.
Relations between Roman Catholicism and other religious communities
A Catholic dogma, Extra Ecclesiam Nulla Salus (literally "no salvation outside the Church") has sometimes been interpreted as denying salvation to non-Catholic Christians as well as non-Christians, though Catholic teaching has long stressed the possibility of salvation for persons invincibly ignorant (through no fault of their own) of the Catholic Church's necessity and thus not culpable for lacking communion with the Church. In the 20th century this inclusive approach was expressed in the condemnation of Feeneyism and in the declaration of the Second Vatican Council, which said that "the plan of salvation also includes those who acknowledge the Creator," although this is ambiguous and numerous interpretations have arisen. Vatican II further affirmed that salvation could be available to people who had not even heard of Christ (cf. Acts 17:23)— but that all who gain salvation do so only by membership in the Catholic Church, whether that membership is ordinary (explicit) or by extraordinary means (implicit).
