The angels who were cast down to hell, were also sons of God. 2 Peter 2:4
Not relevant to the discussion.
Peter warns the Church by this example, as he goes on to say in 2 Peter 2...
For if God did not spare the angels who sinned, but cast them down to hell and delivered them into chains of darkness, to be reserved for judgment... in this same vein of though, Peter goes on to warn... 20 For if, after they have escaped the pollutions of the world through the knowledge of the Lord and Savior Jesus Christ, they are again entangled in them and overcome, the latter end is worse for them than the beginning. 21 For it would have been better for them not to have known the way of righteousness, than having known it, to turn from the holy commandment delivered to them. 2 Peter 2:4, 20-21
There is nothing in this passage that says anything about eternal life, salvation, or the loss of either.
How about the marriage relationship between the Church and the Lord?
30 For we are members of His body, of His flesh and of His bones. 31 “For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh.”32 This is a great mystery, but I speak concerning Christ and the church. 33 Nevertheless let each one of you in particular so love his own wife as himself, and let the wife see that she respects her husband. Ephesians 5:30-33
One would have to completely ignore the possibility of divorce, through marital unfaithfulness to believe in OSAS.
Unless there is any evidence in Scripture warning believers of being divorced from Christ, and resultant loss of salvation, there is zero reason to believe in such a thing.
And…only only has to recall God's view of marriage; it is PERMANENT. Why did Moses allow certificates of divorce? Because of the hardness of the peoples' hearts.
Jesus explained God's view of marriage in Matt 19:1-5. And then said this, in v.6 - So they are no longer two, but one. Therefore
what God has joined together, let man not separate.”
So your suggestion of spiritual divorce is way out of line according to God's view.
Not only that, Jesus explained WHY divorce was granted in v.7-8: 7 “Why then,” they asked, “did Moses command that a man give his wife a certificate of divorce and send her away?” 8 Jesus replied, “Moses permitted you to divorce your wives because your hearts were hard. But
it was not this way from the beginning.
So trying to use the excuse of divorce in the believer's position as "Bride of Christ" to deny eternal security is just extremely unbiblical.
God's view of divorce proves that even when speaking of the Bride of Christ and the groom, divorce cannot be an issue.
Further, in God's laws, it was the man who issued a certificate to his wife. For divorce to be an issue in the debate over eternal security, one would have to argue that Jesus can divorce His Bride. Since we know God's view of divorce, that is not even possible.
Your doctrine seems to teach that it is impossible for there to be a divorce.
I believe that has been thoroughly proven from Scripture. God condemns divorce.
As Jesus said regarding divorce; "it was not this way from the beginning" (Matt 19:8). And "what God has joined together, let not man separate" (Matt 19:6).
But all this talk about divorce is just a distraction away from the real issue: God's gift of eternal life is irrevocable, just as justification is.
All who have believed have been sealed with the Holy Spirit of PROMISE, a GUARANTEE for the day of redemption.
I don't know how that could be said any more clear.
None of this has been refuted. Rejected, yes, but refuted? No.
