Can you show me were they said that baptism results in regeneration because I have already shown you an example in Acts 8:9-21 where Phillip baptized Simon, but later it was discovered by Peter that Simon was not regenerate.
Sure

I would love to.
:bible1: Titus 3:5 Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;
6: Which he shed on us abundantly through Jesus Christ our Saviour;
7: That being justified by his grace, we should be made heirs according to the hope of eternal life.
This one I obviously already used, but wished to put up again. the “washing of regeneration” refers to baptism. Here, scripture tells us that it is He saved us. How did He save us? by the washing of regeneration. By baptism.
Note, while I know we disagree on when one is born again, I hope you can see that although Catholics would say “baptism saves us”, it is because we believe this is WHEN the saving blood of Christ is applied to the individual. It is not just an empty ritual but we truly believe this is when the blood of Christ makes us His children.
:bible1:John 3:
5: Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
The water and spirit both refer to baptism. They go together.
:bible1:1Cor 6:
11 And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.
It is the washing of baptism that gives birth to sanctification and justification, and is not just a symbolic act.
I also like this one.
:bible1:Acts 22:
16: And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on the name of the Lord.
Be baptized. Why? to wash away your sins.
There are many more. I will post a link.
Sacrament of Baptism. Some I do not find as compelling as others, but what I do find compelling is the consistency of interpretation of scripture.
Because basically that is what we have here. It is not that Catholics do not have scripture and we pull this belief out of “traditions of men”. But we do in fact believe that this has been passed on since the time of the apostles, can point to scripture that we interpret to support this, and can also point to other Christians, very early Christians who have a consistently Catholic interpretation of scripture.
So what you are asking me to replace the Catholic interpretation of Scripture with your interpretation which is seen nowhere in Christian writings until the last 400 years. And that is not something I can do since scripture specifically warns of those who will come along with false teachings.
You believe you have scripture. I believe I have scripture.
But I also have the history of other Christian writings that show the Catholic interpretation is the one Christians had followed since the time of the apostles.
