Catholicism and American Freedom: A History is a readable, scholarly work, with extensive references. Although it is a history of Catholicism, one also gets an education on the great influence of all Christian religions on US historical development, which is woefully lacking in modern, politically correct textbooks. (One can learn here how Justice Felix Frankfurter invented the "wall of separation of church and state," which did not exit before 1948.)
There are a couple of threads to the book. One is the struggle of Catholics to gain acceptance as loyal Americans first from Protestant antagonism, which has ebbed and flowed over two centuries, to the attacks by secular liberalism, today. The book opens in 1859 with Protestants questioning Catholic motives because of the refusal of a Catholic child in a public school to recite the Protestant enumeration of the Ten Commandments. One hundred years later, in that same state (Massachusetts), Catholics were berated for inflicting their views of contraception on non-Catholics. In the mid-1800s, the Church saw slavery as an acceptable institution (though not in its form in the American South); by the late 1960s, the Church was a leader for racial equality. Also, since the early 1900s, the Church began leading the campaign for social justice in the US. Today, the Catholic Church finds itself aligned with conservative Protestants against secular liberals' insistence on legal abortion. The final chapter of the book is about the post-Vatican II Church's handling of internal problems, such as pederasty by priests, and its effect on the Church's mission in America. This section is weak, but the scenario is still being played out.
A second thread is the struggle by the institutional Church to come to grips with democracy, and with individual freedom, which is the hallmark of American democracy. In early American history, the Church was suspicious of democracy because of the persecution of Catholics and seizure of Church property by European democracies, and the Church favored governments that sponsored Catholicism as the state religion. Though it took over a century, the American experience was a major influence on changing the Church's thought to realize that freedom of religion is better for the Church and that individual freedom in a democracy is preferred over authoritarian rule.
