False premise.
Can you go into a bit more detail? For instance, most Christians would claim Jesus Christ was absolutely perfect, indicating that everyone else was, by degrees, falling short of perfection. Saints are higher on the perfection scale than run-of-the-mill folks (being more like Christ and all), while folks like Uncle Joe Stalin would probably fall much farther down on the scale of perfection. I understand the term "perfect" implies an absolute -- however with a definition of perfection ("like God") one should be able to rate where folks fall in the quest for perfection; hence one should be able to claim someone to be "more perfect" than another, implying their relative positions on the perfection scale.
