Can I add to this forum?
To understand paedobaptism, we have to understand about baptism is it’s purpose.
Baptism in its true nature is “emersion” weather full or partial. John baptized by water; however, there is one greater that comes that will baptize by the Holy Spirit. (Luke 3:16)
I argue that biblically the symbolism of actual baptism is as 100% described in Romans 6. burried (entirely/spiritually) with Christ and risen in a newness of life. This is described seemgly at conversion not birth. Infact, the supernatural account of baptism is not done with water, but with the Holy Sprit. I argue that water baptism is simply an outward representation of an inward reality. (You are dead to sin and alive in Christ where the acts of the believer is characterised by a newness of life through the works of the Holy Spirit). You hate the things God hates and love the things God loves. Not because you have to, but because it is who you are now. (See the new conenant). I could go on an on about regeneration itself, but it directly relates to baptism as a symbol of regeneration.
Is being baptized by water necissary for salvation? I argue no… bible does not give
water baptism as a salvation preqrequisite, which is left to the hands and decisions of men; however, you should get water baptized IF you are indeed regenerated (changed) and as a testimony confession of what has happend to you… It does say, though, baptism by the **Holy Spirit ** IS
part of salvation (Mark 16:16). It is a part of when God said he would remove your heart of stone and put in a heart of flesh Eze 36:26 and backed up by Romans 6, Galatians 5. Notice how one is controled by man and the other controled by God… People don’t like God to be in control…
Let me give you probably the biggest contrast as an example of Water baptism and Holy Sprit baptism. Do a search for the versus in the new testament about “Circumcision and Uncircumsission”, read the chapters and how it relates to regeneration and baptsim. You will see what I mean.
Water baptism does not bring on Holy Spirit baptism, only God brings Holy Sprit baptism. This is evidenced when a church was baptizing with water and the Paul comes and baptises them with the Holy Spirit. Which one do you think is the one being talked about in Mark 16:16? Therefore… Salvation does not get imputed to babies nor does it affect their spiritual walk with God. Nor does Man have power over or decision of salvation or conversion.
Now here’s the question paedobaptists have to answer… Where in babie’s life, born in sin is they being revealed the grace of God and has been transformed by the Holy Spirit?
The potential concequence of paedobaptism is this:
A congregation go on pretending they are Saved because one time they were baptized because their parents took them a infants to a Priest/Pastor who declared them saved. Where is God in this?
Now, although not in the bibe either, I don’t see dedication harmfull.

A parental promise to God you will raise your children under the Lordship of Christ and be an example to them.
Hopefully that makes sense, if you want more actual biblical references to anything I said, please let me know.
