I’m not familiar with Kreeft … but I’ve already aptly given my opinion on the concept of relativism. I think it’s a fallacious concept – and if you begin with a flawed premise from the outset; then everything that follows will probably be pretty useless.
As I’ve said – I believe religious values have been just as subjective (throughout history) as secular values. After all liberty as we understand it today, equal rights, justice, and so on are secular concepts – not theistic concepts. The march towards the liberty we value so highly today began through protest and revolution. First protest against theocracy, then revolt against a tyrannical monarchy, then our own struggles (in the United States anyway) for individual liberty.
No, the Church has always held the same deposit of faith throughout history (however many of her doctrines developed over time due to unsavory circumstances that required a clearer understanding of the faith). There have been many occasions of which the Church was tested and tried and found wanting (but Jesus himself said that the weeds would be planted alongside the wheat).
“But while everyone was sleeping, his enemy came and sowed weeds among the wheat, and went away.” Matt. 13:25
The Church has failed numerous times to live up to her own standards (those set by Christ) because it did not reside in a vacuum (she like everyone else was part of a society that was continually in transition). So yes, she did make mistakes but not the kind of which you state, there was no tyranny (if by tyranny you mean the Church had no right to protect her faithful from heretical views), there was not theocracy. A theocracy would entail a total authority of which the Church never had for it recognized the monarchies as rightful rulers. If you knew more than just the caricature of history promulgated by public school systems you would know this. You would also know, for example, that it was the Church who came up with the concept of equality under natural law for all men:
An excerpt taken from: “How the Catholic Church Built Western Civilization” by Thomas E. Woods Jr. Ph. D
“At this point, the king, faced with dramatic testimony regarding Spanish behaviour in the New World, called together a group of theologians and jurists to develop laws that would govern Spanish officials in their interaction with the natives. In this way were born the Laws of Burgos (1512) and the Valladolid (1513), and similar arguments influenced the so-called New Laws of 1542. Much of this legislation on behalf of the natives proved disappointing in its application and enforcement, particularly since so much distance separated the Spanish Crown from the scene of activity in the New World. But this early criticism helped to set the stage for the more systematic and lasting work of some of the great sixteenth century theological jurists.”
“Among the most illustrious of these thinkers was Father Francisco Vitoria. In the course of his own critique of Spanish policy, Vitoria laid the groundwork for modern international law theory, and for that reason is sometimes called “the father of international law,” a man who propose[d] for the first time international law in modern terms.” With his fellow theological jurists, Vitoria “defended the doctrine that all men are equally free; on the basis of natural liberty, they proclaimed their right to life, to culture, and to property.” In support of his assertions Vitoria drew from both Scripture and reason. In so doing he “furnished the world of his day with its first masterpiece on the law of nations in peace as well as in war.” It was a Catholic priest, therefore, who brought forth the first grand treatise on the law of nations- no small accomplishment."
“In sum, Spanish theologians of the sixteenth century held the behavior of their own civilization up to critical scrutiny and found it wanting. They proposed that in matters of natural the other peoples of the world were their equals, and that the commonwealths of pagan peoples were entitled to the same treatment that the nations of Christian Europe accorded to one another. That Catholic priests gave Western civilization the philosophical tools with which to approach non-Western peoples in a spirit of equality is quite an extraordinary thing.”
It was not atheism or any other “ism” that gave equality before the law, but the equality under natural law as was put forth by Spanish theologians of 16th century:
Now compare this to Nicolo Machiavelli (an atheist) who presaged the arrival of the modern state with his short book “The Prince”.
“For Machiavelli, the state was indeed a morally autonomous institution, whose behavior on behalf of its own preservation could be judged against no external standard, whether the decrees of a pope or any code of moral principle. No wonder the Church condemned Machiavelli’s political philosophy so severely: it was precisely this view that the great Catholic theologians of Spain so emphatically denied. The state, according to them, could indeed be judged according to principles external to itself, and could not act on the basis of mere expedience or narrow advantage if moral principles were trampled in the process.”
