while those of the Gentiles who came to believe and have faith in Christ Jesus (Israel), they were "grafted into" Him (like Luke, whole cities, Cornelius and his household, etc).
These were indicted into the Body of Christ, which did not exist prior to Pentecost. We cannot equate the ecclesia of Israel with the Body of Christ.
That there is a difference between the two groups is clear in that the new man has a place and beginning in time:
Ephesians 2:15
King James Version (KJV)
15 Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace;
Gentiles did not get grafted into an existing provision, because the provision that was in place was done away with. Relationship with God was through the Covenant of Law, which was abrogated with the establishing of the New Covenant, which also has a place and beginning in time which can be precisely established through Christ's Work:
Luke 22:20
King James Version (KJV)
20 Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.
What of the Temple?
1 Corinthians 3:9 - For we are labourers together with God: ye are God's husbandry, [ye are] God's building.
1 Corinthians 3:16 - Know ye not that ye are the temple of God, and [that] the Spirit of God dwelleth in you?
1 Corinthians 3:17 - If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which [temple] ye are.
1 Corinthians 6:19 - What? know ye not that your body is the temple of the Holy Ghost [which is] in you, which ye have of God, and ye are not your own?
2 Corinthians 6:6 - And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in [them]; and I will be their God, and they shall be my people.
Ephesians 2:21 - In whom all the building fitly framed together groweth unto an holy temple in the Lord:
1 Peter 2:5 - Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.
Revelation 3:12 - Him that overcometh will I make a pillar in the temple of my God, and he shall go no more out: and I will write upon him the name of my God, and the name of the city of my God, [which is] new Jerusalem, which cometh down out of heaven from my God: and [I will write upon him] my new name.
(See also 2 Thessalonians 2:4)
I would agree, the Church is the Temple of God.
That doesn't negate the other Temples mentioned in Bible Prophecy.
Revelatoin 11:19 - And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament : and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
Was the Church "opened" at this time?
Jesus own "Body" is the Temple:
But he spake of the temple of his body. - John 2:21
See also the True Heavenly Temple - Exodus 25:40, 26:30, 27:8; Hebrews 8:5, 9:23; Revelation 11:19 and so on.
The Temple represented an earthly parable of the True, which is Heaven itself, the realm of God. When we keep a clear context and properly maintain a Biblical understanding of the purpose of the Temple, we better understand that it was the presence of God that was lacking in man's existence:
Hebrews 9:8-12
King James Version (KJV)
8 The Holy Ghost this signifying, that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing:
9 Which was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience;
10 Which stood only in meats and drinks, and divers washings, and carnal ordinances, imposed on them until the time of reformation.
11 But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building;
12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
It is true that Christ's Body is the Temple spoken of. It is true that the Church is the Temple of God.
But that does not negate the True Holy Place which prior to Christ's Work was not accessible by man.
That does not negate what Revelation, as well as Old Testament Prophecy describes concerning the earthly Temples.
If Scripture states there will be a Temple in the Tribulation, and it does...
Revelation 11
King James Version (KJV)
1 And there was given me a reed like unto a rod: and the angel stood, saying, Rise, and measure the temple of God, and the altar, and them that worship therein.
2 But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months.
...and it states it in Daniel...
Daniel 12:11
King James Version (KJV)
11 And from the time that the daily sacrifice shall be taken away, and the abomination that maketh desolate set up, there shall be a thousand two hundred and ninety days.
...and the Lord states there will be one as well...
Matthew 24:15
King James Version (KJV)
15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand
...who is it that would deny there is going to be a Temple in the Tribulation?
Well, perhaps those that deny the Tribulation, maybe.
All those looking for a new physical Temple to be built in the land of Palestine/Judea in war-torn earthly Jerusalem, have followed cunningly devised fables of Romanism, through the Jesuit Futurist propaganda and counter-reformation theology, of the likes of Manuel De Lacunza, Francisco Ribera, Cardinal Robert Bellarmine, etc. Do not believe me? It is documentable and traceable to them.
On the contrary, despite the fact that questionable scholars and theologians have embraced a view that teaches a Temple in the Tribulation, that does not negate the fact that Scripture itself teaches this.
Usually the denial comes from those who spiritualize Scripture to make it fit their particular theology.
When we see condemnation levied against others to ratify our own doctrine, we have to question that. When we see the Word of God presented to support our views, that's when the discussion begins.
And I look forward to it.
Malachi 3:16
King James Version (KJV)
16 Then they that feared the Lord spake often one to another: and the Lord hearkened, and heard it, and a book of remembrance was written before him for them that feared the Lord, and that thought upon his name.
God bless.
