Augustine of Hippo : This people of God, freed from a great and broad Egypt, is led, as through the Red Sea, that in baptism it may make an end of its enemies. For by the sacrament as it were of the Red Sea, that is by baptism consecrated with the blood of Christ, the pursuing Egyptians, the sins, are washed away. — EXPLANATION OF THE Psalms 107.3 Gregory of Nyssa : Again, according to the view of the inspired Paul, the people itself, by passing through the Red Sea, proclaimed the good tidings of salvation by water. The people passed over, and the Egyptian king with his host was engulfed, and by these actions this Sacrament was foretold. For even now, whensoever the people is in the water of regeneration, fleeing from Egypt, from the burden of sin, it is set free and saved; but the devil with his own servants (I mean, of course, the spirits of evil), is choked with grief, and perishes, deeming the salvation of men to be his own misfortune. — ON THE BAPTISM OF CHRIST Origen of Alexandria : How troublesome a trial it is to pass through the midst of the sea, to see the waves rising up in a heap, to hear the roar and crash of the raging billows; but nevertheless, if you follow Moses, that is, the law of God, the waters will become for you a wall on the right hand and on the left, and you will find a path through dry ground in the midst of the sea. But that heavenly journey too, which we have said the soul makes, may perhaps have some waters as well; it may be that there too waves are found; for there is a certain portion of waters above the heaven and a certain portion beneath the heaven, and we for the present endure the waves and billows of these waters that are beneath the heaven. — HOMILIES ON Numbers 27.10
