[5] The assistance of Catholic French troops during the American Revolution helped to abate anti-Catholic sentiment in all of the 13 original colonies.

[9] Two of the parishes that Eustace founded were established specifically for African-American Catholics; St. Monica's in Atlantic City and St. Bartholomew's in Camden.

[12] When St. Bartholomew's fell into financial difficulties, Eustace recruited comedian Eddie Cantor to give a benefit performance for the parish in 1950.

[18] Following McCarthy's death in 1959, Pope John XXIII named Celestine Damiano, the apostolic delegate to South Africa, as the third bishop of Camden in New Jersey (with the personal title of archbishop) in 1960.

[19] That same year, Damiano launched a drive to raise $5 million for the construction and improvement of Catholic secondary schools in the diocese.

[20] Damiano initiated the diocese's Brazil mission project in 1961, and the House of Charity Appeal for funding diocesan human services in 1964.

[24] The diocese built nursing homes and established two residences for the elderly, Victorian Towers and St. Mary's Village.

At the time, Follieri was negotiating with the Diocese of Camden and other US and Canadian dioceses to buy churches with Burkle's money and then sell the properties for later profit.In September 2008, Follieri pleaded guilty to federal conspiracy, wire fraud, and money laundering charges, and received a 4+1⁄2-year prison sentence.

[37] John P. Connor was arrested in October 1984 on charges of sexually assaulting a 14-year-old boy when he was a teacher at Bishop Eustace Preparatory School in Pennsauken.

In a pretrial intervention with the local prosecutor, the diocese in 1984 sent Connor to the Southdown Institute in Holland Landing, Ontario, for eight months of psychological treatment.

[41] The Catholic dioceses in New Jersey in February 2019 released the names of clergy who had been credibly accused of sexually abusing children since 1940.

[43] In July 2020, the Diocese of Camden suspended future payments to victims of clergy sexual abuse, citing the financial impact stemming from the COVID-19 pandemic.

[47] In April 2022, the diocese agreed to pay $87.5 million to settle its abuse claims, one of the largest such settlements in the United States.
