The Significance and Importance of Baptism with Water.
Denied and repudiated by the heretical Vatican II Church and the equally heretical so-called ‘traditional’ sects.
Symbols of the Holy Spirit
694 Water. The symbolism of water signifies the Holy Spirit’s action in Baptism, since after the invocation of the Holy Spirit it becomes the efficacious sacramental sign of new birth: just as the gestation of our first birth took place in water, so the water of Baptism truly signifies that our birth into the divine life is given to us in the Holy Spirit. As “by one Spirit we were all baptized,” so we are also “made to drink of one Spirit.”27 Thus the Spirit is also personally the living water welling up from Christ crucified28 as its source and welling up in us to eternal life.29 Link
Epistle of Saint Paul to the Romans 6,3:4
Know you not that all we, who are baptized in Christ Jesus, are baptized in his death?  For we are buried together with him by baptism into death; that as Christ is risen from the dead by the glory of the Father, so we also may walk in newness of life.  For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection.
St. John Chrysostom. Homilies on John 6,3:5
What saith He? “Verily I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the Kingdom of God.” What He declares is this: “Thou sayest that it is impossible, I say that it is so absolutely possible as to be necessary, and that it is not even possible otherwise to be saved.” For necessary things God hath made exceedingly easy also. The earthly birth which is according to the flesh, is of the dust, and therefore heaven641 is walled against it, for what hath earth in common with heaven? But that other, which is of the Spirit, easily unfolds to us the arches642 above. Hear, ye as many as are unilluminated,643 shudder, groan, fearful is the threat, fearful the sentence.644 “It is not (possible),” He saith, “for one not born of water and the Spirit, to enter into the Kingdom of heaven”; because he wears the raiment of death, of cursing, of perdition, he hath not yet received his Lord’s token,645 he is a stranger and an alien, he hath not the royal watchword. “Except,” He saith, “a man be born of water and of the Spirit, he cannot enter into the Kingdom of heaven.”
Remove thyself from that which is common and familiar; a different kind of childbirth bring I into the world; in another manner will I have men to be generated: I have come to bring a new manner of Creation. I formed (man) of earth and water; but that which was formed was unprofitable, the vessel was wrenched awry;649 I will no more form them of earth and water, but ‘of water’ and ‘of the Spirit.’…
And if any one asks, “How of water?” I also will ask, How of earth? How was the clay separated into different parts? How was the material uniform, (it was earth only,) and the things made from it, various and of every kind? Whence are the bones, and sinews, and arteries, and veins? Whence the membranes, and vessels of the organs, the cartilages, the 87 tissues, the liver, spleen, and heart? whence the skin, and blood, and mucus, and bile? whence so great powers, whence such varied colors? These belong not to earth or clay. How does the earth, when it receives the seeds, cause them to shoot, while the flesh receiving them wastes them? How does the earth nourish what is put into it, while the flesh is nourished by these things, and does not nourish them? The earth, for instance, receives water, and makes it wine; the flesh often receives wine, and changes it into water. Whence then is it clear that these things are formed of earth, when the nature of the earth is, according to what has been said,650 contrary to that of the body? I cannot discover by reasoning, I accept it by faith only. If then things which take place daily, and which we handle, require faith, much more do those which are more mysterious and more spiritual than these. For as the earth, which is soulless and motionless, was empowered by the will of God, and such wonders were worked in it; much more when the Spirit is present with the water, do all those things so strange and transcending reason, easily take place…
[2.] Do not then disbelieve these things, because thou seest them not; thou dost not see thy soul, and yet thou believest that thou hast a soul, and that it is a something different besides 651 the body.
Let us then believe the declaration of God; that is more trustworthy than actual seeing. The sight often is in error, it is impossible that God’s Word should fail; let us then believe it; that which called the things that were not into existence may well be trusted when it speaks of their nature. What then says it? That what is effected is a Generation. If any ask, “How,” stop his mouth with the declaration of God,667 which is the strongest and a plain proof. If any enquire, “Why is water included?” let us also in return ask, “Wherefore was earth employed at the beginning in the creation of man?” for that it was possible for God to make man without earth, is quite plain to every one. Be not then over-curious…
That the need of water is absolute and indispensable,668 you may learn in this way. On one occasion, when the Spirit had flown down before the water was applied, the Apostle did not stay at this point, but, as though the water were necessary and not superfluous, observe what he says; “Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we?” (Acts x. 47.)
In Baptism are fulfilled the pledges of our covenant with God;670 burial and death, resurrection and life; and these take place all at once. For when we immerse our heads in the water, the old man is buried as in a tomb below, and wholly sunk forever;671 then as we raise them again, the new man rises in its stead.672 As it is easy for us to dip and to lift our heads again, so it is easy for God to bury the old man, and to show forth the new. And this is done thrice, that you may learn that the power of the Father, the Son, and the Holy Ghost fulfilleth all this…
To show that what we say is no conjecture, hear Paul saying, “We are buried with Him by Baptism into death”: and again, “Our old man is crucified with Him”: and again, “We have been planted together in the likeness of His death.” ( Rom. vi. 4, 5, 6.) And not only is Baptism called a “cross,” but the “cross” is called “Baptism.” “With the Baptism,” saith Christ, “that I am baptized withal shall ye be baptized” ( Mark x. 39 ): and, “I have a Baptism to be baptized with” ( Luke xii. 50 ) (which ye know not); for as we easily dip and lift our heads again, so He also easily died and rose again when He willed or rather much more easily, though He tarried the three days for the dispensation of a certain mystery…
Let us then who have been deemed worthy of such mysteries show forth a life worthy of the Gift, that is, a most excellent conversation;673 and do ye who have not yet been deemed worthy, do all things that you may be so, that we may be one body, that we may be brethren. For as long as we are divided in this respect, though a man be father, or son, or brother, or aught else, he is no true kinsman, as being cut off from that relationship which is from above. What advantageth it to be bound by the ties of earthly family, if we are not joined by those of the spiritual? what profits nearness of kin on earth, if we are to be strangers in heaven? For the Catechumen is a stranger to the Faithful. He hath not the same Head, he hath not the same Father, he hath not the same City, nor Food, nor Raiment, nor Table, nor House, but all are different; all are on earth to the former, to the latter all are in heaven. One has Christ for his King; the other, sin and the devil; the food674 of one is Christ, of the other, that meat which decays and perishes; one has worms’ work for his raiment, the other the Lord of angels; heaven is the city of one, earth of the other. Since then we have nothing in common, in what, tell me, shall we hold communion? Did we remove the same pangs,675 did we come forth from the same womb? This has nothing to do with that most perfect relationship. Let us then give diligence that we may become citizens of the city which is above. How long do we tarry over the border,676when we ought to reclaim our ancient country? We risk no common danger; for if it should come to pass, (which God forbid!) that through the sudden arrival of death we depart hence uninitiated,677 though we have ten thousand virtues, our portion will be no other than hell, and the venomous worm, and fire unquenchable, and bonds indissoluble.
The latter is a total refutation of the heresy of the salvation of even catechumens, never mind Protestants, Muslims and Buddhists, by Baptism of Desire.
Anyone, who believes and teaches the heresies of salvation by Blood, Desire and Invincible Ignorance, believes they are too are a god, which was the sin of Adam. In fact, they are presumptuous enough to believe that they are even better than God, because they believe that the clear teachings of Our Lord Jesus Christ, God Incarnate, on the necessity of Baptism with Water and the Holy Ghost and Faith for salvation are unfair and unjust and that they, mere men, are wiser, more merciful and more just than God!
