Argentine Catholic Apostolic Church

In 1973 Pedro Ruiz Badanelli (1899–1985) was consecrated as an ICAA bishop by Morizio Dominguez. Badanelli was a notable former priest of the Roman Catholic Archdiocese of Santa Fe, Argentina, an academic canon lawyer, founder of university departments, and dissident Catholic supporter and friend of President Juan Perón. In 1958, Badanelli wrote, in his book Perón, La Iglesia y un Cura, that he rejected the idea of an Argentine state religion similar to the Church of England, and denied the rumour that in 1960 ICAB Bishop Carlos Duarte Costa clandestinely consecrated him in Buenos Aires. Nevertheless Badanelli later adhered to the ICAA.

The Argentine Catholic Apostolic Church began as a project of apparent religious support for right-wing extremism,[5] But with the end of the National Reorganization Process (the last military dictatorship) in 1983, the ICAA was deregistered from the National Register of Religions. By this time Morizio Dominguez had consecrated José Eugenio Tenca Rusconi (c. 1930–2003), a former Roman Catholic priest, as a bishop, who in turn later consecrated many of the current ICAA bishops. In 1992 Tenca Rusconi ordained Dante Luis Bergonzi Moreno (1965–) to the priesthood and consecrated him as a bishop three years later. Bergonzi Moreno became the bishop–primate of ICAA. Tenca Rusconi also consecrated Ramón Frías, Eduardo Lencina, Gustavo Gabucci, and a Monsignor Arnedo as bishops. Bergonzi Moreno, in turn, has consecrated Carlos Walter Vich Pizarro and Carlos Adrian Guedes Dominguez as bishops.

"Almost as long as it has existed, ICAA has fallen victim to the balkanization effect–internal schisms, splinters and defections–which had become a key feature of the ICAB as well. In the ICAA’s early days it was almost simultaneously called the American Catholic Apostolic Orthodox Church (...). As time progressed, the number of ICAA splinter groups soared; Congregation of Mary Mystic Rose; Liberal Apostolic Church of Christ; Charismatic Catholic Movement; Congregation of Worker Priest Missionaries; Congregation of Saint Joseph the Worker; Dissident Augustinian Congregation; Dissident Apostolic Christian Priests; Missionary Church of Evangelization–Order of the Holy Spirit, etc. etc."[6]
