The following is my response to a brother trying to prove baptismal regeneration::
Honestly brother, if this is your only “proof” of such a major doctrinal claim, it is enormously subjective. The passage clearly also equates, in context, our death with Christ’s death. That is clearly a typological/spiritual reality not a literal one. Baptism is an outward expression of an inward change. We are born again not by water (natural birth) but by the indwelling of the Spirit (salvation; John3). Baptism is a matter of obedience and a picture. Spiritually being dunked or sprinkled does not magically confirm gracious blessings for there is not a single scripture.
Appeals may be made to various theologians or preachers or even early church fathers but their words are not the inspired Word.
Further, your entire argument is built upon the meaning of a Greek word, if you cant make your point through Scriptures clear meaning in context then what do you do with these scriptures?
“Keep reminding God’s people of these things. Warn them before God against quarreling about words; it is of no value, and only ruins those who listen.” 2 Timothy 2:14
“knowing this first, that no prophecy of Scripture is of any private interpretation” 2 Peter 2:20
If we have to quarrel about words and appeal to “hidden meanings,” we have wandered from simplicity
“Be diligent to present yourself approved to God, a worker who does not need to be ashamed, rightly dividing the word of truth.” 2 Timothy 2:15
I still gotta disagree with you on the grounds of scripture
“Unless I am convinced by the testimony of the Scriptures and by clear reason (for I do not trust in the pope or councils alone, since it is well known that they have often erred and contradicted themselves), I am bound by the Scriptures I have quoted. My conscience is captive to the Word of God. I cannot and I will not retract anything, since it is neither safe nor right to go against conscience. May God help me. Amen.” – Luther
