They can be. Case in point:
Fr. Gustavo Gutierrez’s recent death was highlighted in America Magazine. The article, written by Michael E. Lee stated, “Perhaps more than any other theological figure of the past century, this humble Peruvian priest, who died October 22 at the age of 96, wrestled with the question he identified at the heart of Liberation Theology: “How do you tell the poor, “God loves you.””

Fr. Gutierrez wrote the book, A Theology of Liberation.

Liberation Theology stresses the need to care for the poor out of a sense of justice as much as charity. It also stresses, consistent with Pope Francis, that we should not only offer preferential treatment to the poor, but also learn from them. Funny, I was raised to believe that the only thing the poor could teach me was how to avoid getting there.

Liberation Theology has produced a number of martyrs in South America. It has also been a persistent thorn in the side of those who would insulate the Church from thorny issues such as justice.

I would say that Fr. Gutierrez’s Powerful Question was indeed “dangerous.”
