Pope Benedict XVI
Excerpts from the Encyclical Letter, Spe Salvi, paragraphs 10-11
But then the question arises: do we really want this—to live eternally? Perhaps many people reject the faith today simply because they do not find the prospect of eternal life attractive. What they desire is not eternal life at all, but this present life, for which faith in eternal life seems something of an impediment. To continue living for ever —endlessly—appears more like a curse than a gift…
…Obviously there is a contradiction in our attitude, which points to an inner contradiction in our very existence. On the one hand, we do not want to die; above all, those who love us do not want us to die. Yet on the other hand, neither do we want to continue living indefinitely, nor was the earth created with that in view. So what do we really want?… Saint Augustine, in the extended letter on prayer which he addressed to Proba, a wealthy Roman widow and mother of three consuls, once wrote this: ultimately we want only one thing—”the blessed life”, the life which is simply life, simply “happiness”. In the final analysis, there is nothing else that we ask for in prayer…. But then Augustine also says: looking more closely, we have no idea what we ultimately desire, what we would really like…. We do not know what we would really like; we do not know this “true life”; and yet we know that there must be something we do not know towards which we feel driven.
…This unknown “thing” is the true “hope” which drives us, and at the same time the fact that it is unknown is the cause of all forms of despair and also of all efforts, whether positive or destructive, directed towards worldly authenticity and human authenticity. The term “eternal life” is intended to give a name to this known “unknown”.
