From the article:
Pope Benedict told the Brazilian bishops that while direct involvement in politics is the responsibility of the laity, “when the fundamental rights of the person or the salvation of souls requires it, pastors have a serious duty to make moral judgments even in political matters.”
Certain actions and political policies, such as abortion and euthanasia, are “intrinsically evil and incompatible with human dignity” and cannot be justified for any reason, the pope said.
While some may claim they support abortion or euthanasia to defend the weak and the poor, “who is more helpless than an unborn child or a patient in a vegetative or terminal state?” he said.
“When political positions openly or covertly include plans to decriminalize abortion and euthanasia, the democratic ideal – which is truly democratic only when it acknowledges and safeguards the dignity of every human person – is betrayed at its foundations,” Pope Benedict told the bishops.
