Pope Francis has issued a lengthy sermon on the topic of holiness. He used the form of an Apostolic Exhortation, which is like pastoral advice to Christians. This is opposed to an Encyclical, which would have ecclesiastically binding requirements for the Catholic Church. This Exhortation, Gaudete et Exultate ("Rejoice and Be Glad") has caused ructions among the conservative leadership of the Catholic Church, which is almost always the case with anything Francis writes or speaks.
What upsets them with Gaudete et Exultate boils down to just a few sentences from a document with five sections and 177 paragraphs. The upsetting comments apply specifically to the U.S., though other countries should take notice as well. Evangelical Christians in the U.S. come under the same criticism Francis is leveling at American Catholics. Let's look at the issues that are so concerning to conservative Christians in this country.
