The Eucharist is the only sacrament for the "purpose of public demonstration." (your words in quotes)
If I said that it was a spelling error. The Eucharist is part of our confession, for purposes of remembrance. We are remembering that Christ already lives inside us, enabling us to benefit from his redemption. We'll live sanctified lives and have Eternal Life in our glorification as a result. In this sense, we're remembering how we should live, and what our hope is.
In my view, the Eucharist is not a mystical, legal participation in Christ in the act itself, but only a display of our Christian right to access Christ as a matter of confession. It is a kind of ritualistic confession, like reciting a creed in dramatic form. It clearly obtains its meaning in the act by our willingness to confess and display its symbolic truths.
I Cor 11:26 For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until He comes.
The reason "public proclamation" is in the Eucharist, the Christian is ACTIVE in taking the sacrament as in "Take Eat" and "Take Drink." We do not have anywhere in Scripture this kind of statement of public proclamation concerning baptism....the recipient is passive. No where does Scripture even hint that Baptism is public proclamation. You even admitted it. And anyone stating as such....is adding to Scripture.
I've only admitted that "common sense" by definition does not require elaboration or delineation. You might as well explain that I'm using a device to communicate to you right now. Do I need to validate that by proving it from Scripture? No. Neither does Water Baptism have to be proven from Scripture that it is a public display of Christian conversion.
When we're asked to "confess our sins to one another," do we need to prove that our sins are not being kept private? Neither do we need to prove that Baptism is a public proclamation. Not only does one have to perform it, but the context of these references seem to indicate a public setting.
Lutherans, Calvinists, Anglicans, Roman Catholics, Orthodox and Methodists FLATLY REJECT THIS DEFINITION OF BAPTISM. Baptism as a Public Proclamation is a post-reformation interpretation gained prominence here in American in the 18th Century onwards. And it has a bite of American nationalism to it also....after all what is more American than Mom, homemade apple pie, base ball and Baptist theology?
As I said, I hold to Reform truths up to a certain point. The Apostles and the Scriptures trump the Reformers. I showed you where I disagree with both Luther and Zwingli. They had issues in their time, and we have issues in our own time. We should focus on our commonalities, and try to figure out where and why we have differed?
I believe in Water Baptism the way perhaps Zwingli did, that it was symbolic. Whether we call it a "means of grace" is subject to how we interpret that term?
I was baptized as an infant--I believe it was more a Dedication than a Baptism. I was later submerged as an adolescent repenting from my backsliding--I don't believe this Baptism was necessary as if I was a new convert from paganism. I had been a Christian from birth.
I think Christians in history have made the same mistake the Jewish leaders did in Jesus' time. They made overly mystical and overly legalistic certain ritual practices that ordinarily seemed pretty "spiritual."
They produced Sacraments and then declared, with supposed "Scriptural Authority," that they were required as a "means of grace." Baloney to both the Pharisees and the Catholic/Reform view of the sacraments as the "means of grace."
The Eucharist was a memory device, a kind of confession of our belief that we have directly ingested Christ into our nature. And Baptism was an initiation ceremony for new converts--a public recanting of previous practices in the society, a public confession of faith in Jesus.
Please demonstrate from Scripture a clear text that shows baptism as "public proclamation." Keeping in mind you stating there was none.
Well, that's pretty silly! You say I've stated there are none, and yet ask me for some?? I don't believe I've denied there is any Scriptural evidence that Water Baptism is a public profession? What I do know I've said is that it is a common sense issue and doesn't really require of me that I research the Scriptures to prove it.
Acts 2.41 Those who accepted his message were baptized, and about three thousand were added to their number that day.
I would agree with you that Baptism does not *have to* be so public. The Ethiopian got baptized only in the presence of Philip. But it is something to be done and recognized, both personally and witnessed to by somebody. And in effect, as I've seen it in my life, it can be a very public proclamation of one's choice to convert to Christianity.
Baptism is no more necessary to conversion than a marriage ceremony is necessary to make a marriage. The marriage consists of a vow. The marriage ceremony is required only as a matter of formality.
Similarly, Jesus required Water Baptism early on of his immediate Disciples. There is no extensive theology on the subject for purposes of formalizing it in history. Whether it needed to be done for those raised up in Christ is not an issue even raised. How it is to be administered, immersed or dipped, is not even delved into.
It is an initiation ceremony for people who had been living as pagans. It formalized their conversion in front of a witness or in public. It is less important than what it represents--conversion to Christ.
