How we cite our quotes:
Quote #7
It is right for me to think this way about all of you, because you hold me in your heart, for all of you share in God's grace with me, both in my imprisonment and in the defense and confirmation of the gospel. (Philippians 1:7, NRSV)
Even as it is meet for me to think this of you all, because I have you in my heart; inasmuch as both in my bonds, and in the defence and confirmation of the gospel, ye all are partakers of my grace. (Philippians 1:7, KJV)
This isn't a metaphor—Paul is literally in prison. Though he's free through his faith in Christ, the Roman authorities have other ideas. This is just one of the many times Paul has landed in lock-up for spouting his views about this new messiah. We guess freedom really isn't free.
Quote #8
Let the same mind be in you that was in Christ Jesus, who, though he was in the form of God, did not regard equality with God as something to be exploited, but emptied himself, taking the form of a slave, being born in human likeness. (Philippians 2:5-7, NRSV)
Let this mind be in you, which was also in Christ Jesus: Who, being in the form of God, thought it not robbery to be equal with God: But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men. (Philippians 2:5-7, KJV)
Paul has more thoughts (surprise!): Before, being a slave was bad. Now, it's a good thing. While we shouldn't be slaves to the law and the world, it's totally fine to be slaves to each other and God. After all, it's what Jesus would do.
Quote #9
I am bold enough in Christ to command you to do your duty, yet I would rather appeal to you on the basis of love—and I, Paul, do this as an old man, and now also as a prisoner of Christ Jesus. I am appealing to you for my child, Onesimus, whose father I have become during my imprisonment. (Philemon 1:8-10, NRSV)
Though I might be much bold in Christ to enjoin thee that which is convenient, Yet for love's sake I rather beseech thee, being such an one as Paul the aged, and now also a prisoner of Jesus Christ. I beseech thee for my son Onesimus, whom I have begotten in my bonds. (Philemon 1:8-10, KJV)
Paul's back in the slammer here. Maybe that's why he relates to the plight of Onesimus. They're both metaphorically free through their faith, but they're physically in bondage.
