Obviously, you do not believe that baptism is a means of grace, that it is a sacrament. I do believe that it is and that my Lutheran theology agrees with St. Paul's.
BTW, "sacramentarian" historically was the term used to describe those who held to a non-sacramental view of the Lord's Supper, i.e., the Zwinglians and Calvinists, who denied the real presence of Christ's Body and Blood in the Sacrament.
Baptism is not, as some teach, essential to salvation. Paul reminds the Corinthians that they were saved through believing the gospel he preached: "How that Christ died for our sins according to the scriptures; and that he was buried, and that he rose again the third day according to the scriptures..." (1 Cor 15:3). Paul repeatedly declares that we are saved only by believing the gospel. For example: "For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to everyone that believeth [it]" (Rom 1:16). It is the gospel that saves, not baptism. Salvation comes through believing the gospel, not by being baptized. In fact, Paul declared, "For Christ sent me not to baptize, but to preach the gospel" (1 Cor 1:17). Clearly baptism is no part of the gospel and thus has nothing to do with salvation and not one verse in the Bible can be found to support the notion! Admittedly, Mark 16:16 says, "He that believeth and is baptized shall be saved," intimates only that saved people get baptized (setting aside the order specified). The rest of the verse says, "but he that believeth not shall be damned." making it clear what place baptism has with respect to salvation. Nowhere does the Bible say, "He that is not baptized shall be damned," or "If you only believe but don't get baptized you are lost." There are scores of verses that say, "He that believeth is saved," but only one that says, "He that believeth and is baptized is saved." And scores of verses declare that if we don't believe the gospel we are lost—but not one says that if we are not baptized we are lost.
Jesus Christ is the Savior of the world, yet as John 4:2 tells us, He never baptized anyone. If He didn't even baptize one then He obviously took care not to do so for a specific reason: If the Savior of the world who did all that was necessary for our salvation baptized no one, then baptism clearly has nothing to do with salvation! The thief on the cross was never baptized.
Then wouldn't it be best to baptize everyone as infants? No, that is a fraud. To the question, "What doth hinder me to be baptized?" Philip replied, "If thou believest with all thine heart, thou mayest" (Acts 8:36-37). Baptism is for believers, and no infant has made that choice. "Then they that gladly received his word were baptized" (Acts 2:41); "When they believed...they were baptized" (8:12); "many of the Corinthians hearing believed, and were baptized" (18:8). Baptism is a public declaration of faith in Christ, an act of obedience to Christ's command, and thus required of every Christian—but is does not save the soul; it follows salvation.
Jesus said that we must be "Born again of water and of the Spirit"? to Nicodemus, not merely any old rabbi but member of the Sanhedrin; to the Jew baptism would be meaningless. That notwithstanding, Christ made no bones about Nicodemus' stupidity in not comprehending being born again. Israel had ordinances of "washing with water for cleansing" the priests or a leper or someone who had been defiled (cf. Exo 30,40; Lev 13,15, etc.). So Christ was saying that "cleansing from sin" and a special work of the Holy Spirit were essential to being born again. Ephesians 5:26 explains that the New Testament fulfillment of Old Testament water cleansing is "the washing of water by the word." Peter says we are "born again...by the word of God" (1 Pt 1:23). Paul calls it "the washing of regeneration and renewing of the Holy Ghost" (Tit 3:5); i.e., "born of water and the Spirit."
It was to Israel that John the Baptist preached "the baptism of repentance for the remission of sins" (Mar 1:4, etc.), which they understood in the context of Old Testament water cleansing. Baptism was also connected with the "remission of sins" when offered to Jews in the Book of Acts (whether preached by Peter on the Day of Pentecost (2:38), or to Saul (22:16). That this was associated with Israel's practice of water cleansing, and not an indication that the physical act of baptism saves anyone, is clear for the reasons already given and in the context of all of the scriptures.
The idea that baptism is essential to salvation comes from Roman Catholicism. Vatican II declares, "By baptism men and women are cleansed from original sin and from all personal sins, they are born again as children of God...." (Vatican Council II, Costello Publishing, Vol 2, p 561); "Baptism is also to be given to infants...[that] they may be reborn of water and the Holy Spirit to divine life in Christ Jesus" (Vol 2, p 391), "Baptism, which is necessary for salvation...frees us from original sin and communicates to us a share in divine life" (Vol 2, pp 111-12). Not true!
The Bible is very clear that the Old Testament sacrifices and other physical acts, such as circumcision, tithing or keeping the Sabbath, could not pay the debt demanded by God's justice for sin. They were symbolic of the coming sacrifice of Christ and the heart response of faith required for salvation. Judaism's great error was its sacramentalism and formalism: finding salvation in the mere act of prayer, ritual and other deeds rather than in repentance and faith. Matthew 15 and 23 give examples of Christ's scathing rebuke of Jewish religious leaders for this error that led millions astray.
Christ criticized the rabbis for giving God His "tithe" even from the herbs in their gardens, while neglecting "judgment, mercy and faith." He quoted God's rebuke of Israel through Isaiah: "This people draweth nigh unto me with their mouth, and honoureth me with their lips: but their heart is far from me." To make a physical act/ritual efficacious for salvation makes it impossible to trust Christ for salvation. It must be either/or. It can't be both.
The church has only two ordinances (not sacraments): baptism and communion, or the Lord's supper. Neither is efficacious for forgiveness of sins or salvation. Both are symbolic of the believer's identification with Christ in His death, burial and resurrection. To imagine that either has merit as a physical act repeats the error of Judaism. Yet such is the great heresy of Roman Catholicism—it offers salvation through sacraments, which are physical rituals ministered by the priests.
Offering salvation through baptism or any other physical act is a serious heresy which we must stand against without compromise. The eternal destiny of souls is at stake. We dare not remain silent.
For the record, Calvinism is a doctrine straight from the pit of hell. Neither is there any "presence" in the bread or wine (real, imputed or otherwise).
