This issue’s lineup of articles prompts the question: Would it have been possible even to fantasize about this lineup back in 1965? I think not. Fifty years ago, on September 14 (Exaltation of the Cross), Vatican II’s fourth and final session opened and, by closing time, promulgated 11 of the council’s 16 documents. Important as are the earlier documents (e.g., Sacrosanctum concilium and Lumen gentium), one might argue that the latest ones really mark the Church of the future: e.g., Gaudium et spes, Ad gentes, Nostra aetate, and Dignitatis humanae.
