1Cor 15:4 And that he was buried, and that he rose again the third day according to the scriptures:
5 And that he was seen of Cephas, then of the twelve:
6 After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep.
If we put together the four gospels... this is how they will end.... (I believe the 500 witnesses are in this group). Here is how that happened...
Then the eleven disciples went away into Galilee, And he led them out as far as to Bethany, into a mountain where Jesus had appointed them. And when they saw him, they worshipped him: but some doubted. And Jesus came and spoke unto them, saying, All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. And he said unto them, Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved; but he that believeth not shall be damned. And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues; They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover. And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me. For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence. When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel? And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power. But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
So then after the Lord had spoken these things unto them, he lifted up his hands, and blessed them. And it came to pass, while he blessed them, while they beheld, he was taken up; he was parted from them, and carried up into heaven, he was received up into heaven, and a cloud received him out of their sight, and sat on the right hand of God. And they worshipped him. And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel; Which also said, Ye men of Galilee, why stand ye gazing up into heaven? This same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven.
And they returned with great joy unto Jerusalem from the mount called Olivet, which is from Jerusalem a Sabbath day's journey. And were continually in the temple, praising and blessing God. And they went forth, and preached everywhere, the Lord working with them, and confirming the word with signs following.
And there are also many other things, many other signs, which Jesus truly did, in the presence of his disciples, which are not written in this book: And, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name. Amen.
Every time someone was baptized in the Bible, it was never done in the literal name of “Father, Son and Holy Ghost
