During the 1980s and 1990s, some claimed that followers of the Priestly Union of Saint Jean-Marie Vianney constituted the majority of the Catholics of Campos, who had never known the revised Liturgy of the Mass, as their diocesan bishop Antônio de Castro Mayer had, during the 1970s, retained the Tridentine Mass in his territory. However, when at the end of 2003 separate statistics were, for the first time, gathered for the Diocese of Campos and the new personal apostolic administration, the latter reported 28,325 Catholics, 28 priests, 9 seminarians, 75 religious sisters and 24 schools, while the diocese reported 854,000 Catholics, 48 diocesan and 17 religious priests, 30 seminarians, 19 religious brothers and 67 religious sisters, and 5 schools ("Annuario Pontificio" 2005). The corresponding figures seven years later were, for the personal apostolic administration, 30,733 Catholics, 32 priests, 7 seminarians, 38 religious sisters and 24 schools, and for the diocese 940,000 Catholics, 69 diocesan and 16 religious priests, 27 seminarians, 18 religious brothers and 81 religious sisters and 18 schools.
