The Trinity in the Bible and the Quran

Matthew 28:19
" Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit,"

Notice in the quoted passage the word, "name," a singular word referring to Allah, yet followed by three names:  1)  "Father,"  2) "Son,"  and 3) "Holy Spirit."  Since the beginning of the Christian faith, the Apostles and those whom they instructed have understood this to mean one God...in three persons.  This has never been understood by Catholics or Orthodox Christians to referr to three seperate gods, but rather one and only one God.

In the Greek, the phrase  "the name of the Father and the Son and the Holy Spirit is:

τὸ ὄνομα τοῦ πατρὸς καὶ τοῦ υἱοῦ καὶ τοῦ ἁγίου πνεύματος

in which τὸ ὄνομα (to onoma, the name) is in the accusative case and τοῦ πατρὸς (tou patros, the Father), τοῦ υἱοῦ (tou uiou, the Son) and τοῦ ἁγίου πνεύματος (tou hagiou pneumatos, the Holy Spirit) are all in the genitive case.

Koine Greek is a very grammatically precise language and the picture being painted here is one of a single fork with three prongs as follows:

                                                 -----τοῦ πατρὸς (tou patros, the Father)
τὸ ὄνομα (onoma, name)---------------τοῦ υἱοῦ (tou uiou, the Son)
                                                 -----τοῦ ἁγίου πνεύματος (the Holy Spirit)

This is EXACTLY what the Trinity is, One God in three persons. Each member of the Trinity is a distinctive person and is God individually and the combination of the three is also God.

This is why Jesus Christ could say:

I and the Father are one John 10:30 because Jesus Christ as the Son (Prong 2) is just as much God as is the Father (Prong 1).

This is the true oneness of God, and just as the Jews of Jesus' day did not understand this:

31The Jews picked up stones again to stone Him. 32Jesus answered them, “I showed you many good works from the Father; for which of them are you stoning Me?” 33The Jews answered Him, “For a good work we do not stone You, but for blasphemy; and because You, being a man, make Yourself out to be God.” John 10:31-33

So Muhammad also did not understand it:

They have certainly disbelieved who say that Allah is Christ, the son of Mary. Surah 5:17

This is nothing more than the same unbelief that the Jews of Jesus' day manifested.
