Is Messiah Married to the gentile "church"?

NO!

Isaiah 62:2-4
​For ZION'S SAKE will I not hold my peace, and for JERUSALEM'S SAKE I will not rest, until the righteousness thereof go forth as brightness, and the salvation thereof as a lamp that burneth.
2 AND THE GENTILES SHALL SEE THY RIGHTEOUSNESS, and all kings thy glory; and thou shalt be called by a new name, which the mouth of the Lord shall name.
3 Thou shalt also be a crown of glory in the hand of the Lord, and a royal diadem in the hand of thy God.
4 Thou shalt no more be termed Forsaken, neither shall thy land any more be termed Desolate; but thou shalt be called HEPHZIBAH and thy land BEULAH: for the Lord delighteth in thee, AND THY LAND SHALL BE MARRIED.
Revelation 21:-
2 And I, John, saw the holy city, NEW JERUSALEM, coming down from God out of Heaven, PREPARED AS BRIDE adorned for her husband.
3 And I heard a great voice out of Heaven, saying, “Behold, the tabernacle of God is with men, and He will dwell with them; and they shall be His people, and God Himself shall be with them and be their God.
4 And God shall wipe away all tears from their eyes, and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain; for the former things are passed away.”
This proves God still has ZION in mind and the land New Jerusalem is the bride! The gentile "church" is NOT the bride, but New Jerusalem itself is the bride!
The people of Zion shall be called HEPHZIBAH, meaning-My delight is in thee. and the Land itself shall be called BEULAH-
Meaning. married. Beulah (/ˈbjuːlə/ BEW-lə), a feminine given name, originated from the Hebrew word (בְּעוּלָ֑ה bə'ūlāh), used in the Book of Isaiah as a prophesied attribute of the land of Israel. The King James Bible transliterates the word and translates it as "married" (see Isaiah 62:4).
