Ferraz left the Brazilian Catholic Apostolic Church in 1958. Ferraz reconciled with the Catholic Church in 1959 and his episcopal consecration was recognized as valid. However, Ferraz was excluded from church affairs such as the Roman Synod of 1960, even though he was present in Rome at the time, while the Vatican belatedly questioned the legitimacy of having recognized his status. Shortly thereafter, in 1961, Costa died and the ICAB underwent several years of tumult as dissensions, schisms, and multiple claimants to the patriarchal throne threw the church into disarray. After this period, the church found stability and growth under Mendez, Costa's successor.
