The early Church not only taught repentance unto salvation (by faith in the Risen Lord Jesus and His shed blood), they also taught baptism in water and baptism in the Holy Spirit, subsequent to salvation...
This was what ALL new converts in the early Church experienced, today, the vast amount of Church leave out baptism in water and baptism in the Holy Spirit, which is folly.
1 cor 15
1¶Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3¶For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4And that he was buried, and that he rose again the third day according to the scriptures:
eph 1
13¶In whom ye also
trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
14Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
Rom 10
8But what saith it? The word is nigh thee,
even in thy mouth, and in thy heart: that is, the word of faith, which we preach;
9That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
10For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
11For the scripture saith, Whosoever believeth on him shall not be ashamed.
12For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
13For whosoever shall call upon the name of the Lord shall be saved.
14¶How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?
15And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!
Now I don't say 'don't baptise people ' because we should .
But look at the explanation of how we appropriate salvation and how the Gospel is defined and described.
Notice The order in Eph 1 .13
The definition in 1cor 15 andhow we appropriate in Romans 10 ,9
Just like in Johns Gospel , Acts ,Romans Galations , and many other books and letters the focus is 'believe ' . Through faith , by Faith , trust ect . Water has nothing to do with salvation nor does anything else than ' believe '.
