There is an interview at Catholic News Agency with Rev. Robert Sirico and Dr. Steven Schneck about the Tea Party movement and Church teaching. Here is a small excerpt:
Fr. Sirico described the Tea Party as "an amorphous thing" with a lot of variety and as a "populist, spontaneous movement." He thought its common themes include a desire for less government and a desire "to limit the power that politicians have over peoples' lives."
Fr. Sirico had his own criticisms of the movement. He thought charismatic leaders could lead people in the wrong direction, and the Tea Party's lack of a "historical memory" of past mistakes means that it lacks safeguards against plausible-looking proposals that "end up being harmful." Some Tea Party rhetoric suggests it has no role for government to serve the poor.
