If you have not been baptized in the name of Jesus Christ, you have not been baptized at all, and similarly, if you were not baptized by complete emersion on your back into a watery grave you have not been baptized at all as well. So why do I say that?
First of all, baptism in the name of Jesus Christ is the doctrine that is exclusively taught and practiced in the Bible. When we look at what is taught and what is practiced in the Bible it becomes crystal clear why I said what I said at the beginning.
Secondly, look at the definition of baptism. It is the immersion or submersion of a person in water. The root of the word for baptize in the Greek is "baptizo", which means "to immerse, submerge; to make whelmed (i.e. fully wet)". This meaning does not allow for water to be sprinkled or poured on a person when baptized.
Jesus answered him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.” Nicodemus said to him, “How can a man be born when he is old? Can he enter a second time into his mother's womb and be born?” Jesus answered, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God (John 3:3-5 ESV). Note: Born of water is baptism in the name of Jesus Christ.
Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved (Acts 4:12).
And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him (Colossians 3:17).
Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost (Acts 2:38).
Know ye 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 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 6:3-4).
Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead (Colossians 2:12).
He that believeth and is baptized shall be saved; but he that believeth not shall be damned (Mark 16:16).
Now I would remind you, brothers, of the Gospel I preached to you, which you received, in which you stand, and by which you are being saved, if you hold fast to the word I preached to you—unless you believed in vain. For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, that He was buried, that He was raised on the third day in accordance with the Scriptures (1 Corinthians 15:1-4) ESV). Note: As part of obeying the Gospel, we must be "buried" by being baptized in the name of Jesus Christ.
For as many of you as have been baptized into Christ have put on Christ (Galatians 3:27).
Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water. The 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 ( 1 Peter 3:20-21).
But Jesus said, It should be done, for we must carry out all that God requires. So John agreed to baptize him. After his baptism, as Jesus came up out of the water, the heavens were opened and he saw the Spirit of God descending like a dove and settling on him (Matthew 3:15-16 NLT). Note: Jesus came out of the water so he had been fully immersed.
Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls (Acts 2:41).
And immediately there fell from his eyes as it had been scales: and he received sight forthwith, and arose, and was baptized (Acts 9:18).
And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on the name of the Lord (Acts 22:16). Note: this is part of Paul's testimony
For as yet He was fallen upon none of them: only they were baptized in the name of the Lord Jesus (Acts 8:16).
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 (Acts 8:38). Note: the Eunuch and Philip went down into the water so they were fully immersed.
Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we? And he commanded them to be baptized in the name of the Lord. Then prayed they him to tarry certain days Acts 10:47-48).
And when she was baptized, and her household, she besought us, saying, If ye have judged me to be faithful to the Lord, come into my house, and abide there. And she constrained us. (Acts 16:15)
And he took them the same hour of the night, and washed their stripes; and was baptized, he and all his, straightway (Acts 16:33).
And Crispus, the chief ruler of the synagogue, believed on the Lord with all his house; and many of the Corinthians hearing believed, and were baptized (Acts 18:18).
When they heard this, they were baptized in the name of the Lord Jesus (Acts 19:5).
Let's examine Matthew 28:19 to understand what I just stated. We need to examine it in full context to understand what Jesus was commanding:
And Jesus came and said to them, “All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.” (Matthew 28:18-20 ESV).
In Matthew 28:18, Jesus told his eleven disciples that He had all authority in heaven and on earth, and we know that there is only One who has authority and that is God, as there is only One God (Deuteronomy 6:4, Mark 12:29). In other words, Jesus was making it clear to the eleven disciples that He is God.
In Matthew 28:19 notice that when Jesus said "name" it was singular, not plural and that if the Father, the Son and the Holy Ghost were actually names, that He would have said "names", not name. In fact though, the Father, the Son and the Holy Ghost are not names but are titles of God. So once again, He was telling them that He is God.
So what did the eleven Apostles do with this command? Approximately ten days later, on the day of Pentecost, when the crowd asked them "Men and brethren, what shall we do?" (Acts 2:37), the apostle Peter, representing the other ten apostles that were present when they heard Jesus speak the Great Commission verses (Matthew 28:18-20), told the crowd of about 3000 (Acts 2:41) to be baptized in the name of Jesus Christ for the remission of sins (Acts 2:38). It is way beyond obvious, so absolutely clear, that the apostles knew that the name of the Father, the Son, and the Holy Ghost is Jesus Christ.
If you have been duped by a priest or pastor that doesn't understand this truth, like I was (see My Testimony), and have truly not been baptized, you can readily be re-baptized in the name of Jesus Christ, just like John the Baptist's disciples were in Acts 19:5.
Also there are pastors and ministers who think they are clever and can outsmart God by baptizing "in the name of the Father, the Son, the Holy Ghost, and Jesus Christ", but don't be fooled by their deceitfulness as you will still not be baptized. Just like there was not one single person baptized in the name of Father, Son, and Holy Ghost in the entire Bible, there was not anybody baptized in the name of the Father, the Son, the Holy Ghost, and Jesus Christ. I know that for a fact as I have read the Bible from cover to cover, over twenty times.
Make sure you are baptized in the name of Jesus Christ for the remission of sins, being fully immersed on your back in water. Then you will not be one of millions who have not been baptized at all.
