Holy See
Although the Holy See is sometimes metonymically referred to as the "Vatican", the Vatican City State was distinctively established with the Lateran Treaty (1929) between the Holy See and Italy to ensure the temporal, diplomatic, and spiritual independence of the Papacy. As such, ambassadors are officially accredited to the Holy See and not the Vatican City State. Conversely, Papal nuncios to states and international organisations are recognised as representing the Holy See and the integrity of the Catholic Church along with its 1.3 billion members, not the Vatican City State, as prescribed also in the Canon law of the Catholic Church (1983). The "Holy See" thus refers to the See of Rome viewed as the central government of the Catholic Church. The Catholic Church, in turn, is the largest non-government provider of education and health care in the world, while the diplomatic status of the Holy See facilitates the access of its vast international network of charities.
Nostra aetate
Nostra aetate () is the Declaration on the Relation of the Church with Non-Christian Religions of the Second Vatican Council. Passed by a vote of 2,221 to 88 of the assembled bishops, this declaration was promulgated on 28 October 1965 by Pope Paul VI. It is the shortest of the 16 final documents of the Council and "the first in Catholic history to focus on the relationship that Catholics have with Jews." It "reveres the work of God in all the major faith traditions." It begins by stating its purpose of reflecting on what humankind have in common in these times when people are being drawn closer together.
