Actually John 3:7 says nothing of what you claimed. "Do not be amazed that I said to you, "You must be born anew.""
1. We will not be born from the church, for we have been born anew spiritually already. We do grow in maturity as we follow the leading of the Holy Spirit after we have been born anew as babes in Christ.
2. The Jerusalem above is our mother, Galatians 4:26, but the Jerusalem above is allegorical being populated with children of the promise, corresponding to children of the free woman and not the bondwomen.
3. No, the church is not called the heavenly Jerusalem, rather the church of the first-born, which corresponds to the church of Jesus Christ. We are "enrolled in heaven" because our names are written in the Lamb's book of life when God spiritually puts us in Christ, being baptized into the body of Christ, the general assembly.
Acts 13:33 God hath fulfilled the same unto us their children, in that he hath raised up Jesus again; as it is also written in the second psalm, Thou art my Son, this day have I begotten thee.
Begotten in this verse is different from John 3:16 only begotten.
What is the context of the word begotten in Acts 13:33? What is it relative to? Whereas you would say of "only begotten" as being an eternal kind of. How about here, is it time/moment specific in Acts 13:33? Just what day was this?
What is the contextual meaning of, my Son to I have begotten.
Did God reproduce himself in the flesh, conceived in the virgin Mary. Did this man child, Jesus, grow into the man Jesus, and die. Was the man Jesus resurrected from the dead by the one who had begotten him as a man child.
Did this resurrected man ascend to heaven and is seated on the right hand of him who had begotten him. Is he as a resurrected spiritual man seated there as our high priest?
Heb 5:4,5 And no man taketh this honour unto himself, but he that is called of God, as Aaron. So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee.
