No, that is not what
Acts 22:16 is saying. On the surface it may seem so, but upon deeper
examination, it does not.
[
Act 22:16 KJV] 16 And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on the name of the Lord.
First, "wash away" is not the same word as "forgive" if that's what you're implying. To "wash away" is to have one's sinful beliefs washed away by the water of the truth of the gospel and in the receiving of it; that is, through the preaching and teaching of the gospel (and through the Holy Spirit), Paul's understanding/ beliefs/perceptions changed regarding the basis of salvation as a man cannot forgive his own sins, but which would have been the case and Christ would not be the Saviour, had "wash away" meant forgive. Paul's sin which was to be "washed away" was his belief from within by his old conscience - a sinful belief in law and works for salvation (which up to then had been the foundation of his life), unto a belief in Christ as Saviour. However, only by first being forgiven, was it possible for it to be washed away, otherwise, impossible. This is an entirely different matter than of God forgiving one's sins. The washing away came after his salvation which had already occurred, and through salvation alone, was sin his forgiven -- the washing away was not that.
Second, the "baptism", was a baptism unto the name of the Lord Jesus, but only as a physical and symbol act (having no spiritual efficacy of itself), and was not true spiritual baptism, which baptism was placed upon his spirit by the Holy Spirt, not upon his flesh. We know this because the baptism of the verse was from a man to a man, not from God to a man. This spiritual baptism had already occurred on the road to Damascus from God.
Third, "calling on the name of the Lord", would occur through his newly acquired faith in the Lord which was imparted to him through the Holy Spirit and realized by him by preaching/teaching. Through the presence of the Holy Spirit, that teaching found place within him, and by that, his conscience came to know Jesus Christ, and he called upon the name of the Lord. It is by this same cause that everyone who becomes saved calls upon the name of the Lord - there is no other way to know the Lord but by becoming saved.
Fourth, in
Acts 9:18 even before Paul's baptism, the scales fell from Paul's eyes. Since it was before his physical baptism, scales falling from his eyes signifying that the Holy Spirit (who had been given unto Paul on the road to Damacus) was already present within Paul and no one besides Jesus Christ had caused it. We can know this, because man cannot dictate to God or force when someone is to be baptized in the spirit.
I don't understand your reference to
Rom 6: 3- 4 - relates to Acts.
[
1Pe 3:21 KJV]
21 The like figure whereunto [even] baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a
good conscience toward God,) by the resurrection of Jesus Christ:
[
Heb 10:2,
22 KJV]
2 For then would they not have ceased to be offered? because that the worshippers once purged should have had
no more conscience of sins. ...
22 Let us draw near with a true heart in full assurance of faith, having o
ur hearts sprinkled from an evil conscience, and our bodies washed with pure water.
[
2Co 1:12 KJV] 12 For our rejoicing is this,
the testimony of our conscience, that in simplicity and godly sincerity, not with fleshly wisdom, but by the grace of God, we have had our conversation in the world, and more abundantly to you-ward.
[
1Ti 1:5 KJV] 5 Now the end of the commandment is charity
out of a pure heart, and [of] a good conscience, and [of] faith unfeigned:
[
Tit 1:15 KJV]
15 Unto the pure all things [are] pure: but unto them that are defiled and unbelieving [is] nothing pure; but
even their mind and conscience is defiled.
[
Heb 9:9,
14 KJV]
9 Which [was] a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect,
as pertaining to the conscience; ...
14 How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God,
purge your conscience from dead works to serve the living God?
[1Co 12:13 KJV]
13 For
by one Spirit are we all baptized into one body, whether [we be] Jews or Gentiles, whether [we be] bond or free; and have been all made to drink into one Spirit.
[1Co 1:2 KJV] 2 Unto the church of God which is at Corinth, to them that
are sanctified in Christ Jesus, called [to be] saints, with all that in every place
call upon the name of Jesus Christ our Lord, both theirs and ours:
