“Clericalism” in and of itself is best viewed as using the authority of clerical office, be it priest, bishop, cardinal, etc., in order to wield power over others or to use their authority to act hypocritically, by concealing immoral actions, and to silence others.
So, under the shield of clericalism, clergy can perhaps get away with embezzling church funds, having sexual relations, gambling, using drugs, acting cruel towards others, secretly living lavishly, etc.
But amidst this breaking and ongoing abuse scandal (we’ve just seen the tip of the iceberg of it in the US), the term “clericalism” is being overplayed in order to downplay the sexual crimes and infractions of those involved. Let’s put it this way: if there was a massive scandal involving priests selling drugs, getting rich, and covering for each other, everyone would say that the Church has a drug dealing problem first and foremost; nobody would blame “clericalism.” Clericalism would just be the means by which those acts were covered. But the main effort would be focused on eliminating the drug dealers from the Church.
By not calling the problem what it is clearly, the Church is not doing anybody any favors. It seems to be a delay tactic, leaving folks scratching their heads for a while to figure out what it is and how to address it.
