The personal can never be the universal, because of man's unique "giftedness". Some would disagree and think that, as Maslow thought, that man's "needs" are based on a scale of hierarchy. But, anyone that has seen a mother give up her "last morsel of bread", or a stranger act to defend the defenseless, has not known or experienced man's ability to rise above his hierarchal needs.
On the other hand, one cannot presume that a particular individual should act in any particular way, as this would undermine what is needed for altruistic action, which is liberty of choice and value. Man is not made for another man's purposes, but is his own end. The libertarian would defend the right of men to their own personal convictions. Actions come from values, convictions, and most choices are made on a scale of higher or greater values, etc. And these are all individually understood and defined within our society. There is no "one Purpose" .
Today, the pastor admonished his parishnors to embrace the life of faith, in the resurrection and the purposes of God. Faith is a personal choice and decision, once one comes to understand that the "real world" does not function on any other course of action than "real world action", real world solutions, and real world politics. The real world is the political, social, physical, historical, experiential, and cultural one. And free socities do not tend to dictate what or which is of ultimate value, nor define these for the individual, except within the boundaries of law. And the law protects the citizen in their liberty of conscience.
Though the personal can never be the universal, neither can there be a universal understanding of life, as it concerns the individual.
All religions, arts and sciences are branches of the same tree. All these aspirations are directed toward ennobling man's life, lifting it from the sphere of mere physical existence and leading the individual towards freedom.
