The very idea of a Christian political theology is problematic. If human beings are only transitorily on earth, and earth is but a vale of tears through which we must pass on our way to paradise, earthly politics loses almost all value. Life in the polis cannot be the good life for man, since fulfillment lies in the hereafter; here below, we must prepare for eternity. Earthly happiness for rational persons consists in whatever confidence they may entertain about the life hereafter. This "abstentionist” vision is in some ways at odds with the involvement of Christ in the everyday life of the community in which he spent his short life.
