The Apostles therefore, as we have said, being about to separate in order to preach the Gospel, settled upon this sign or token of their agreement in the faith; and, unlike the sons of Noah, who, when they were about to separate from one another, built a tower of baked bricks and pitch, whose top might reach to heaven, they raised a monument of faith, which might withstand the enemy, composed of living stones and pearls of the Lord, such that neither winds might overthrow it, nor floods undermine it, nor the force of storms and tempests shake it. Right justly, then, were the former, when, on the eve of separation, they built a tower of pride, condemned to the confusion of tongues, so that no one might understand his neighbour’s speech; while the latter, who were building a tower of faith, were endowed with the knowledge and understanding of all languages; so that the one might prove a sign and token of sin, the other of faith.
