Society of Saint Pius V

In 1983, Lefebvre expelled four priests (Clarence Kelly, Daniel Dolan, Anthony Cekada, and Eugene Berry) of the SSPX's Northeast USA District from the society, partly because they were opposed to his instructions that Mass be celebrated according to the 1962 Roman Missal issued by John XXIII.

[citation needed] It was their opinion that it included departures from the liturgical traditions of the church (for example, inserting the name of Saint Joseph after that of the Blessed Virgin Mary in the Canon of the Mass).

The eight priests were Thomas Zapp, Donald Sanborn, Anthony Cekada, Daniel Dolan, William Jenkins, Eugene Berry, Joseph Collins, and Martin Skierka.

Cekada states[9] that this resulted from the SSPV's intrinsic distrust of a centralized authority as existed in the SSPX, which makes the latter vulnerable to being "subverted with one stroke of a pen" to the Vatican.

Rather than independent congregations being a weakness and something to be lamented, Cekada considers all such groups and priests taken together preferable to the SSPX, which has continued to hold negotiations with Rome and uses the 1962 Missal.

The SSPV currently has five permanent priories, and its priests serve a network of chapels, churches, and temporary Mass locations in 14 US states (as of 2023[update]) and one Canadian province (Alberta).

The sisters have two additional houses in Melville, New York, and White Bear Lake, Minnesota, where they run schools, and engage in other types of charity work, such as visiting nursing homes.

The congregation operates Immaculate Heart Seminary in Round Top, New York, for its candidates, under the direction of Bishop James Carroll, CSPV.
