Me4Him,
Romans was written not only for Jews or 'Israel'(physical nation), but, also, it was written to the Christians both Jews & Gentiles.
You take verse 4 out of Romans chapter 7 with the context.
The context of Rom. 7:1-6 mentioned about the law. It was written to Jewish believers, that we are not under the laws anymore, but under Jesus Christ through the grace. This context is not discuss about 'Christ's bride'. This conext discusses about the law of the marriage.
The only way you can understand what verse 4 is talking about, first you have to read above verse 3 first. Verse 3 says, "...but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man."
So, it is likewise as verse 4 compared with verse 4 says, "Wherefore my brethren, ye also become DEAD TO THE LAW (through what?-) by the body of Christ; that ye should be married to another, EVEN to him(Christ) who is raised from the dead, that we should bring forth fruit unto God."
To my understanding, at the first, we were bond or slave under the law, when we accept Jesus Christ, then we have to buried our sins or flesh include law, that we are no longer bond or slave(marry) with the law, then now we are married to Jesus Christ, so, we should bring our fruits unto God.
Also, Romans 6:3-5 explaining more clear about dead in Christ uses as the illustration of baptism that we shou,d be buried with Christ, because He was buried for us, then Christ raised from the death, so, we shall be raised with Christ. Notice Romans 6:7-8 explaining more clear about law, it tells us, that a person(follower) which is "dead" is FREED FROM SIN(Law or Slave)." So, next verse says, "Now if we be dead with Christ, we believe that we shall also live with him"
Romans 7:4 does nothing with the comparing of "Church" & "Israel" of Christ's Bride. The context of Romans 7:1-6 discusses about Christ sets us free FROM THE LAW(Bond or Slave or sins).
Understand?
Of course, the word, 'trinity' is not find in the Bible. We all know that. But we all know the Bible does mentioned about trinity of God by use in Matt. 28:18; and ***1 John 5:7-8**** too.
Your arugment with trinity is absence from the Bible comparing with word, 'church' is absence of Revelation chapter 21 is a weakeness.
Use your common sense.
WHO shall dwelling in God's House???
How about John 14:1-3? Isn't our Father's house- New Jerusalem?
Use your common sense!
In Christ
Rev. 22:20 -Amen!
