As Spotlight intimated, orphans and children from poor and broken families, were especially the target of abusive priests in Boston. The ecclesiastical hierarchy intimidated the families, who thought they were unable to fight the money, power, and influence of the clergy. It was a class conflict of the powerful vs. the powerless.
Here are a few thoughts from Isaiah on the matter:
The haughty eyes of people shall be brought low, and the pride of everyone shall be humbled; and the Lord alone will be exalted in that day. For the Lord of hosts has a day against all that is proud and lofty, against all that is lifted up and high; against all the cedars of Lebanon, lofty and lifted up; and against all the oaks of Bashan; against all the high mountains, and against all the lofty hills; against every high tower, and against every fortified wall; against all the ships of Tarshish, and against all the beautiful craft. The haughtiness of people shall be humbled, and the pride of everyone shall be brought low; and the Lord alone will be exalted on that day.
For Jerusalem has stumbled and Judah has fallen, because their speech and their deeds are against the Lord, defying his glorious presence. The look on their faces bears witness against them; they proclaim their sin like Sodom, they do not hide it. Woe to them! For they have brought evil on themselves.
O my people, your leaders mislead you, and confuse the course of your paths. The Lord rises to argue his case; he stands to judge the peoples. The Lord enters into judgment with the elders and princes of his people: It is you who have devoured the vineyard; the spoil of the poor is in your houses. What do you mean by crushing my people, by grinding the face of the poor? says the Lord God of hosts.
Whoever is left in Zion and remains in Jerusalem will be called holy, everyone who has been recorded for life in Jerusalem, once the Lord has washed away the filth of the daughters of Zion and cleansed the bloodstains of Jerusalem from its midst by a spirit of judgment and by a spirit of burning. Then the Lord will create over the whole site of Mount Zion and over its places of assembly a cloud by day and smoke and the shining of a flaming fire by night. Indeed over all the glory there will be a canopy. It will serve as a pavilion, a shade by day from the heat, and a refuge and a shelter from the storm and rain.
