We first learn that "YHVH Elohim" (יְהֹוָ֨ה אֱלֹהִ֧ים) brought Ishah to Ha-Adam, and-"joined" (וְ-דָבַ֣ק) the man to his wife in Bereishit / Genesis 2:22-24. * Later during the ministry of Jesus of Nazareth, we are reminded in Mark 10:9 that the act of being "joined" (συνέζευξεν) in marriage (described in Genesis 2:22-24) is Godly. - However an odd interpretation of Genesis 2:22-24 by the apostle Paul claims physical marriage is not intended by God in [Romans 8:6-8].
Romans 8:6-8 [KJV]
6 For to be carnally minded is death; but to be spiritually minded is life and peace.
7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
8 So then they that are in the flesh cannot please God.
Why would God join man to his wife in order that they become "one flesh" if the act was not holy?
Consider the desires to become one in marriage, when reading [Romans 8:7] “The mind governed by the flesh is hostile to God”. - How can natural desires placed in each of us by Elohim to unite with a spouse [Genesis 2:24] be considered “hostile to God”?
Unlike Paul - Jesus teaches physical marriage (desire to become one flesh) is Godly In Mark 10:7-8 by reciting Bereishit 2:24.
 For this reason a man shall leave his father and mother,  and the two shall become one flesh; so they are no longer two, but one flesh.  Therefore, what God has joined together, no person is to separate.
Bereishit / Genesis 2:24
24Therefore, a man shall leave his father and his mother, and cleave to his wife, and they shall become one flesh. (עַל־כֵּן֙ יַֽעֲזָב־אִ֔ישׁ אֶת־אָבִ֖יו וְאֶת־אִמּ֑וֹ וְדָבַ֣ק בְּאִשְׁתּ֔וֹ וְהָי֖וּ לְבָשָׂ֥ר אֶחָֽד )
Considering Genesis 2:22-24, Mark 10:7-9 & Romans 8:6-8, Did God intend to only "Join" man to his wife - physically or spiritually?
