Peter said that water baptism was a "like figure" of Noah being saved by going through the flood and that as Noah was saved through the flood we are saved through baptism(baptism does now save us).
Actually he said that the flood was a "like figure" to baptism, not the other way around. The flood was a symbol of baptism.
According to Thayers:
1) a thing formed after some pattern
2) a thing resembling another, its counterpart
a) something in the Messianic times which answers to the type,
as baptism corresponds to the deluge (1 Pet 3:21)
Now lets pause for just a moment before we finish the rest of the thought of Peter, the NT is clear that we are saved by FAITH in Christ NOT by being dunked under water,so Peter just made a very misleading statement UNLESS he explains WHAT HE MEANT.
The only reason it's misleading to you is because you are reading this verse and others like it with a "sola-fide" bias. Your working hypothesis is wrong. You've already determined that baptism couldn't possibly be salvific, therefore the verses can't mean what the plain words say, and must be explained away. Tell me what you think about this interpretation:
For God so loved the world that he gave his only Son, that whoever believes in him should not perish but have eternal life. (John (RSV) 3)
Scripture is clear that we are NOT saved by faith alone. Jesus tells the rich, young man that to enter into eternal life, he needs to keep the commandments. Paul tells us that women are saved through childbearing. Peter says baptism saves. And James says flat out that we are NOT justified by faith alone. This verse must, then be interpreted in light of that fact, so "eternal life" must mean something other than Heaven, because Scripture is clear on the fact that we do not get to Heaven by faith alone.
Here is the rest of the thought of Peter about water baptism, Peter said, baptism does now save us NOT(absolute negative)of flesh(the body being water baptized)a putting away of filth(the body being washed of filth in the water)BUT the answer of a good conscience(correct heart condition toward God) by the resurrection of Jesus Christ(faith in what God has provided through Christ.
To interpret in context, we have to look at what Peter was doing here. First of all, verses 18-22 seem to be a tangent from the main point, which is that suffering for doing what's right is a holy thing to do. Peter is not arguing the point that baptism saves, merely mentioning it in passing to emphasize a point. Secondly, he compares the flood to baptism, then CARRIES THE POINT. To interpret properly, this needs to be kept in mind. I have interpreted it in light of this comparison in a previous post so will not do it again here.
So Peter explains what he meant when he said that water baptism saves us, Peter was saying NOT the physical act of being dunked under water because all that can do of itself is wash filth off the flesh(like taking a bath)then Peter further qualifies what he meant by saying BUT(here is what really saves) a good conscience by the resurrection of Jesus Christ(faith in Christ).
I think you should look into the sentence structure of these verses a little closer. The NIV puts it this way:
" 21 and this water symbolizes baptism that now saves you also—not the removal of dirt from the body but the pledge of a clear conscience toward God.
It saves you by the resurrection of Jesus Christ, 22 who has gone into heaven and is at God’s right hand—with angels, authorities and powers in submission to him."
As you can see, "by the resurrection..." is HOW BAPTISM SAVES, not how to have a clear conscience.
Here are other versions that agree:
"21Corresponding to that, baptism now saves you--not the removal of dirt from the flesh, but an appeal to God for a good conscience--through the resurrection of Jesus Christ" (NASB)
"21The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ: (KJV)
"21 And that water is a picture of baptism, which now saves you, not by removing dirt from your body, but as a response to God from a clean conscience. It is effective because of the resurrection of Jesus Christ." (NLT)
There are others, but this should suffice. The bottom line is that, according to these and other Bible scholars, Baptism saves "by (or through) the resurrection..."
If one reads the NT carefully then one can see that water baptism of itself was nothing but a symbol of conversion, to actually have faith in the symbol is the depth of folly, our faith has to be 100% in Christ and His sacrifice or we will not be forgiven period.
All you have to do is PROVE that baptism is a "symbol of conversion" to make your point. I keep waiting for someone to show me a verse that actually says this. No one has because one doesn't exist. Put "symbolic baptism" in the category of "Man Made Doctrine", right along side sola-fide, sola-scripture and invisible church.
The constant teaching of the Church and Scripture says that baptism is salvific, not symbolic.
