From 1867 to 1984, the United States did not have diplomatic relations with the Holy See. Several presidents designated personal envoys to visit the Holy See periodically for discussions of international humanitarian and political issues. Postmaster GeneralJames Farley was the first of these representatives. Farley was the first high ranking government official to normalize relations with the Holy See in 1933 when the Postmaster General set sail for Europe, along with Soviet Commissar of Foreign Affairs Maxim Litvinov on the Italian Liner. In Italy, Farley had an audience with Pope Pius XI, and dinner with Cardinal Pacelli, who was to succeed to the papacy in 1939. Myron Charles Taylor served Presidents Franklin D. Roosevelt and Harry S. Truman from 1939 to 1950. Presidents Nixon, Ford, Carter, and Reagan also appointed personal envoys to the Pope. Also, all of these presidents, in addition to Truman, Eisenhower, Kennedy, Johnson, and all later presidents, along with the first ladies clad in black dresses and veils, have sought the papal blessing, typically during the first few months of their administrations, and usually traveling to the Vatican to do so. On October 20, 1951, President Truman nominated former General Mark W. Clark to be the United States emissary to the Holy See. Clark later withdrew his nomination on January 13, 1952, following protests from SenatorTom Connally and Protestant groups. The official prohibition lasted until September 22, 1983, when it was repealed by the "Lugar Act". The Vatican has historically been accused of being un-American, at least until the presidency of John F. Kennedy. The bulk of the accusation is found in Paul Blanshard's book American Freedom and Catholic Power, which attacked the Holy See on grounds that it was a dangerous, powerful, foreign and undemocratic institution.
1984–present
The United States and the Holy See announced the establishment of diplomatic relations on January 10, 1984. In sharp contrast to the long record of strong domestic opposition, this time there was very little opposition from Congress, the courts, and Protestant groups. On March 7, 1984, the Senate confirmed William A. Wilson as the first U.S. ambassador to the Holy See. Ambassador Wilson had been President Reagan's personal envoy to the Pope since 1981. The Holy See named Archbishop Pio Laghi as the first Apostolic Nuncio of the Holy See to the U.S. Archbishop Laghi had been Pope John Paul II's apostolic delegate to the Catholic Church in the United States since 1980. Relations between President Ronald Reagan and Pope John Paul II were close especially because of their shared anti-communism and keen interest in forcing the Soviets out of Poland. Also, the two men forged a common bond over having survived assassination attempts just six weeks apart in the spring of 1981. Following the September 11 attacks and the beginning of the US war on terrorism from 2001, the Vatican has been critical of the war on terrorism in general, and particularly critical of the US policies in Iraq. On July 10, 2009, President Barack Obama and Pope Benedict XVI met in Rome. A planned relocation of the U.S. embassy to the Holy See to the same location as the U.S. embassy to Italy drew criticism from several former U.S. ambassadors. On March 27, 2014, Obama and Pope Francis met in Rome; this was followed by Pope Francis's 2015 visit to North America in September 2015, where, after visiting Cuba, he came to the U.S., and participated in the World Meeting of Families in Philadelphia, and also visited Washington, D.C., and New York City. and First Lady Melania Trump meeting with Pope Francis, Wednesday, May 24, 2017, in Vatican City. In June 2015, the United States and the Holy See concluded their first inter-governmental agreement which aims at curtailing offshore tax evasion through automatic exchange of tax information.
