Baptized Unto Moses - 1Co_10:1-2

Spiritual Baptism or Water Baptism? - Romans 6:3-4.
"Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? (3) Therefore we are buried with him by (in) baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life."(4) Is this portion of Scripture speaking of water baptism, or spiritual baptism? This is surely not a major point over which Christians should sever fellowship, as many fine teachers have opposing views concerning this verse. Should one hold to spiritual baptism, I doubt very much that I would change their mind. Personally, I believe this is referring to water baptism, as it speaks of "being baptized unto His death." Spiritual baptism is the act of being placed or "baptized" into His body (1 Corinthians 12:13).

"For by one Spirit are we all baptized into one body..."

We believe this is the same spiritual baptism spoken of in Ephesians 4:4-5...

"There is one body (the Church), and one Spirit, even as ye are called in one hope of your calling; (4) One Lord, one faith, ONE BAPTISM."(5) This does not mean there is no water baptism; but, rather, only one baptism into the Spiritual Body of Christ. This is absolute proof one is saved eternally! Once we are in the Body of Christ; we are never taken out. It is true that sin takes a Christian out of fellowship with Christ; but, never out of His Body or possession. That's why Paul said "one baptism"; therefore, once we are saved, we can never be lost! This spiritual baptism into Christ's Body is not evidenced by sight or feeling, but by the sureness of God's promise in His Word. This baptism cannot be seen by the lost as evidence of our faith; but, water baptism can. Therefore, going to Romans 6, we find that this baptism does show the likeness of what our faith is in—the death, burial, and Resurrection of Christ. This likeness by baptism is a testimony that can be observed by the lost, as to our faith. Romans 6:5 seems to be the key to identifying this as water baptism, and not spiritual.

"For if we have been planted together in the LIKENESS of his death, we shall be also in the LIKENESS of his resurrection"

Spiritual baptism reveals, privately, the result of our faith in Christ's death and Resurrection (our position in Christ); while water baptism reveals, publicly, the likeness of His death and Resurrection (our testimony for Christ).

Since a Christian has publicly identified themselves as such; it is God's will that one should grow in the grace and knowledge of the Lord Jesus; and continue to walk in newness of life.  This is what Ephesians 4:4 is speaking of, the beginning of our testimony by baptism; and the continuation of our testimony evidenced by a changed life.

"Therefore we are buried with him by (in) baptism into (unto) death: that like as Christ was raised up from the dead by the glory of the Father, even so we also SHOULD WALK IN NEWNESS OF LIFE." - Romans 6:4
