Colossians 3
17 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.
Acts 4
10 Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole.
11 This is the stone which was set at nought of you builders, which is become the head of the corner.
12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
"Name" is singular in it's usage in these passages.
Romans 16
24 The grace of our Lord Jesus Christ be with you all. Amen.
25 Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,
26 But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:
The only mystery that was kept secret was the name of the Saviour. Everything else concerning His life and His death was known before Jesus was even born. God has called Himself by many names but there is a name above all names: Jesus.
Philippians 2
9 Wherefore God also hath highly exalted him, and given him a name which is above every name:
10 That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;
11 And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
John 5
40 And ye will not come to me, that ye might have life.
41 I receive not honour from men.
42 But I know you, that ye have not the love of God in you.
43 I am come in my Father's name, and ye receive me not: if another shall come in his own name, him ye will receive.
Jesus was God manifested in the flesh. The entire bible is written with reference to Jesus and His salvation. In John 17.6 Jesus said He was given His name by God and that the name also belonged to God. The bible also says we are baptized into "Christ".
Galatians 3
26 For ye are all the children of God by faith in Christ Jesus.
27 For as many of you as have been baptized into Christ have put on Christ.
28 There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.]
John 14
26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
We are baptized into Christ. Father, Son, Holy Ghost are titles or positions, not names. How many people sign their paychecks "Father" or "Son". You can call people by a title, but the relationship becomes more personal when you use their name.
Acts 16
28 But Paul cried with a loud voice, saying, Do thyself no harm: for we are all here.
29 Then he called for a light, and sprang in, and came trembling, and fell down before Paul and Silas,
30 And brought them out, and said, Sirs, what must I do to be saved?
31 And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.
Belief in Jesus and baptism are tied together. The guard was baptized later in this passage. In Acts 8 Phillip spoke with the eunuch and after the eunuch announced his belief in Jesus Phillip baptized him:
Acts 8
29 Then the Spirit said unto Philip, Go near, and join thyself to this chariot.
30 And Philip ran thither to him, and heard him read the prophet Esaias, and said, Understandest thou what thou readest?
31 And he said, How can I, except some man should guide me? And he desired Philip that he would come up and sit with him.
32 The place of the scripture which he read was this, He was led as a sheep to the slaughter; and like a lamb dumb before his shearer, so opened he not his mouth:
33 In his humiliation his judgment was taken away: and who shall declare his generation? for his life is taken from the earth.
34 And the eunuch answered Philip, and said, I pray thee, of whom speaketh the prophet this? of himself, or of some other man?
35 Then Philip opened his mouth, and began at the same scripture, and preached unto him Jesus.
36 And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized?
37 And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God.
38 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.
39 And when they were come up out of the water, the Spirit of the Lord caught away Philip, that the eunuch saw him no more: and he went on his way rejoicing.
