Hmmm...well you might want to check this site out on the view points of the ECF -

Do you believe that baptism is necessary for salvation?? It would seem that many of the ECF of the 2nd & 3rd centuries did, using Jesus' words to Nicodemus about "being born of the water and of the Spirit" as meaning baptism, whereas most commentators are divided on what it means:
Of water and of the Spirit.
Water is emblematical of the public profession of repentance, and the Spirit is the agent that produces the inward change. The meaning, therefore, is, that an entire change in the spiritual condition of the soul must be openly avowed and truly experienced, to fit the sinner for the kingdom of heaven. (Abbott)
Be born of water.
By water, here, is evidently signified baptism. Thus the word is used in Eph 5:26; Tit 3:5. Baptism was practised by the Jews in receiving a Gentile as a proselyte. It was practised by John among the Jews; and Jesus here says that it is an ordinance of his religion, and the sign and seal of the renewing influences of his Spirit. So he said (Mr 16:16), "He that believeth and is baptized shall be saved." It is clear from these places, and from the example of the apostles (Ac 2:38; 8:12; 13:1-52; 28:31,31; 9:18; 10:47; 28:31; 16:15; 28:31; 18:8; 22:16; Ga 3:27), that they considered this ordinance as binding on all who professed to love the Lord Jesus. And though it cannot be said that none who are not baptized can be saved, yet Jesus meant, undoubtedly, to be understood as affirming that this was to be the regular and uniform way of entering into his church; that it was the appropriate mode of making a profession of religion; and that a man who neglected this, when the duty was made known to him, neglected a plain command of God. It is clear, also, that any other command of God might as well be neglected or violated as this, and that it is the duty of everyone not only to love the Saviour, but to make an acknowledgment of that love by being baptized, and by devoting himself thus to his service. But, lest Nicodemus should suppose that this was all that was meant, he added that it was necessary that he should be born of the Spirit also. (Barnes)
Nicodemus not rightly understanding Christ's meaning in the former verse, our Saviour is pleased to explain himself in this, and tells him,
That the birth he spake of was not natural, but spiritual, wrought in the soul by the Spirit of God, whose working is like water, cleansing and purifying the soul from all sinful defilement. (Burkitt)
Born of water and of the Spirit; purified by the Holy Spirit;
of which baptism by water is a divinely appointed symbol. (FBN)
Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
All agree that the birth of the Spirit refers to the inward, or spiritual change that takes place,
and all candid authorities agree that born of water refers to baptism. John the Baptist baptized both Jew and Gentile as a sign of purification by repentance from past sins. Nicodemus would then have certainly understood by the expression, 'born of water,' a reference to this rite of baptism." (PNTC)
Of water and the Spirit. Why does Jesus add ex hudatos (coming up out of water) here? In verse Joh 3:3 we have "anôthen" (from above) which is repeated in verse Joh 3:7, while in verse Joh 3:8 we have only ek tou pneumatos (of the Spirit) in the best manuscripts. Many theories exist. One view makes baptism, referred to by ex hudatos (coming up out of water), essential to the birth of the Spirit, as the means of obtaining the new birth of the Spirit. If so, why is water mentioned only once in the three demands of Jesus (Joh 3:3,5,7)? Calvin makes water and Spirit refer to the one act (the cleansing work of the Spirit). Some insist on the language in verse Joh 3:6 as meaning the birth of the flesh coming in a sac of water in contrast to the birth of the Spirit.
By using water (the symbol before the thing signified) first and adding Spirit, he may have hoped to turn the mind of Nicodemus away from mere physical birth and, by pointing to the baptism of John on confession of sin which the Pharisees had rejected, to turn his attention to the birth from above by the Spirit.
That is to say the mention of "water" here may have been for the purpose of helping Nicodemus without laying down a fundamental principle of salvation as being by means of baptism. (A.T. Robertson)
Except one be born of water and the Spirit.
By far the vast majority of scholars consider the word "water" in this verse as a reference to Christian baptism. The Cambridge Bible says "the outward sign and inward grace of Christian baptism are here clearly given, and an unbiased mind can scarcely avoid seeing this plain fact. This becomes still clearer when we compare Joh 1:26,33, where the Baptist declares, 'I baptize in water,' the Messiah 'baptizeth in the Holy Spirit.'
The fathers, both Greek and Latin, thus interpret the passage with singular unanimity." Water and Spirit are joined at Mt 28:19; Ac 2:38; 19:1-7; Tit 3:5. (TFG)
Except a man be born of water and of the Spirit - Except he experience that great inward change by the Spirit,
and be baptized (wherever baptism can be had) as the outward sign and means of it. (Wesley)
So, as you can see for yourself, there is somewhat a differing of opinion on the necessity of baptism as it relates to salvation.
