Meaning:
Lit. “black mafia” which in Poland does not refer to an African criminal organization but to the Catholic Church. It is by far the largest religious community in the country and has a strong presence and influence on public life, especially in rural areas. Catholic priests wear black cassocks as their everyday work suits hence the expression. It has a strong negative overtone to it and is mainly used by quite numerous Polish anticlericals when criticizing the Church’s alleged wealth, hypocrisy and interference in politics.
