What is baptism?
Baptism is an immersion in water, and is the point at which a repentant believer is forgiven of his sins.
The Mode
The act of baptism is to immerse the person fully under water, and then raise them up again. This is the only method which we have in the New Testament, and is the meaning of the word itself.
Our English word baptism is not a translation of the underlying Greek word, baptizo, which means immerse, but a transliteration, where the sound of the word in the original language is carried over into the English, creating a new word. Why was this done, and the word not translated? The practice dates back at least as far as Jerome’s Latin translation, the Vulgate (390 - 405 AD), where he transliterated the Greek into the Latin. The reason he did this, or whether the practice preceded him, is not known to me. It is easy to see that the act of baptism carries with it a far greater significance than simply the immersion itself, and that this may be the reason Jerome transliterated the word instead of translating it. Whatever the reason may have been, the practice persists to this day.
The definition of the Greek word baptizo is:
Arndt & Gingrich - “…dip, immerse, dip oneself, wash”[1]
Thayer - “To dip repeatedly, to immerge, submerge”[2]
Liddell & Scott - “to dip in or under water”[3]
Abbot-Smith - “…to dip, immerse, sink”[4]
Bullinger - “…to make a thing dipped or dyed. To immerse…”[5]
This definition of baptizo correlates with the examples we have in the New Testament. Mark 1:9-10a states, “And it came to pass in those days, that Jesus came from Nazareth of Galilee, and was baptized by John in the Jordan. And immediately coming up out of the water…,” and like it, Acts 8:38-39a states, “And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him. And when they were come up out of the water…” In both examples, they were in a body of water when the baptism took place, and they came up out of it when they were through. If we were to translate the passage from Acts instead of transliterating it, the meaning is very clear, “And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he immersed him. And when they were come up out of the water…” To baptize, is to immerse.
This definition also correlates with the figure it stands for, a burial with Christ. Romans 6:3-5 states, “Know you not, that so many of us as were baptized into Jesus Christ were baptized into his death? Therefore we are buried with him by baptism into death: that just as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. For if we have been united with him in the likeness of his death, we shall be also in the likeness of his resurrection.” We are buried with him when we are baptized, and are raised to a new life. As a body is put under the ground when it is buried, so we are put under the water when we are baptized.
What is the result?
The result of baptism is our salvation. This is not because of the washing of the body, 1Peter 3:21, but because it is the point at which we are washed in the blood of Christ, which is what saves us.
Revelation 1:5 states, “To Him who loved us and washed us from our sins in His own blood,” and again, Hebrews 13:12 says, “Therefore Jesus also, that He might sanctify the people with His own blood...” It is the blood of Christ which saves us; but in order for us to be saved, there has to be a point at which we are washed in it, for it is evident that not all are saved, but only those who are in Christ. And this point we are shown in the baptism of Paul, “And now why are you waiting? Arise and be baptized, and wash away your sins, calling on the name of the Lord,” Acts 22:16. It is in baptism that we are washed in the blood of Christ.
