I got this comment from an article in The Economist on the latest release of a set of documents from the Vatican Secret Archives. It is a fine non-passionate response from one of the readers criticizing how people unfairly criticize the 2000+ year old Institution.
Like any other institution, organization, or government, the Catholic Church (i.e. the Vatican) has her own documents to keep away from the un-enlightened public. Let he or she be the first one to cast a stone on the Catholic Church who does not have secrets to keep from the undeserved public.
