The Bible says in Deuteronomy 6:4-5, Hear, O Israel: The LORD our God is one LORD: And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might." I read an interesting polemic against the doctrine or teaching of the Oneness of God some time ago. The writer, apparently a biblical scholar of some sort, pointed out that the above referenced scripture in mentioning that God was one, was speaking of the unity of oneness and was not numerical in nature. I looked at the word "one," אחד pronounced ' echâd , in Strong's Hebrew and Greek Dictionary and, sure enough, it does have the connotation of unity. Below is the quote from Strong's Hebrew and Greek Dictionary:
A numeral from H258; properly united, that is, one; or (as an ordinal) first: - a, alike, alone, altogether, and, any (-thing), apiece, a certain [dai-] ly, each (one), + eleven, every, few, first, + highway, a man, once, one, only, other, some, together.
From G863; freedom; (figuratively) pardon: - deliverance, forgiveness, liberty, remission."
Let me be bold to say that no where in the Bible record does anyone use the triune formula in baptism. In the accounts recorded in the Book of the Acts of the Apostles, the only way baptism was carried out was in the name of the Lord Jesus or the name of Jesus Christ, etc. This fully agrees with the statement of the Apostle Peter and the Apostle John in Acts 4:12 when they told the Jewish rulers that there is salvation in no other name, "for there is none other name under heaven given among men, whereby we must be saved." The name of Jesus Christ in baptism is the individual's public confession of his or her repentance toward God and faith toward the lord Jesus Christ. This fully agrees with Romans 10:8-9 which says, "...The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved." It is not optional if one is to have a hope of heaven. If you, my friend, have never repented of your sins, that is turned your life over to God, and if you have never been baptized in the name of the Lord Jesus for (in order to have your sins) remitted or forgiven, let me encourage you to find someone to baptize you today. God has given you the promise that you will receive the Holy Ghost just like they did on the Day of Pentecost. Don't delay, you are only one heartbeat away from eternity.
