(1) The geographical universality of the Deluge may be safely abandoned.
Neither Sacred Scripture nor universal ecclesiastical tradition, nor again scientific considerations, render it advisable to adhere to the opinion that the Flood covered the whole surface of the earth. …
(2) The Deluge must have been anthropologically universal, i.e. it must have destroyed the whole human race.
… *The question, whether all men perished in the Deluge, must be decided by the teaching of the Bible, and of its authoritative interpreter. *As to the teachings of the Bible, the passage which deals ex professo with the Flood (Gen., vi-ix), if taken by itself, may be interpreted of a partial destruction of man; it insists on the fact that all inhabitants of the “land”, not of the “earth”, died in the waters of the Deluge, and it does not explicitly tell us whether all men lived in the “land”. It may also be granted, that of the passages which refer incidentally to the flood, Wis., x, 4; xiv, 6; Ecclus., xliv, 17 sqq., and Matt., xxiv, 37 sqq., may be explained, more or less satisfactorily, of a partial destruction of the human race by the inundation of the Deluge; but no one can deny that the prima facie meaning of I Peter, iii, 20 sq., II Peter, ii, 4-9, and II Peter, iii, 5 sqq., refers to the death of all men not contained in the ark. The explanations of these passages, offered by the opponents of the anthropological universality of the Deluge, are hardly sufficient to remove all reasonable doubt. We turn, therefore, to authority in order to arrive at a final settlement of the question. Here we are confronted, in brief, with the following facts: Up to the sixteenth and seventeenth centuries the belief in the anthropological universality of the Deluge was general. Moreover, the Fathers regarded the ark and the Flood as types of baptism and of the Church; this view they entertained not as a private opinion, but as a development of the doctrine contained in I Peter, iii, 20 sq. Hence, the typical character of both ark and Flood belongs to the “matters of faith and morals” in which the Tridentine and the Vatican Councils oblige all Catholics to follow the interpretation of the Church.
