In 1949, the Brazilian government temporarily suppressed all public worship by the ICAB, because its liturgy and its clerical attire would result in confusion by being indistinguishable from those of the Catholic Church in Brazil and were tantamount to deception of the public. However, a few months later ICAB churches were permitted to reopen, provided that their liturgy would not duplicate the Catholic liturgy, and their clergy would wear gray clerical attire in contrast to the black attire worn by Catholic clergy.
