"There is therefore no condemnation for those who are in Christ Jesus. For the law of the Spirit of life in Christ Jesus has set me free from the law of sin and death." Romans 8:1, 2
Comment (hereafter "C"): Here is the Pauline charter of freedom from the slavery of the old law. Here is the New Exodus. Now what does this freedom mean? It is freedom from anxiety, from fear, from inferiority complexes, from isolation, from egotism, from arrogance, namely from all the things that lead us to the harm of self and others that is sin.
"For freedom Christ has set us free; stand fast therefore, and do not submit again to a yoke of slavery." Galatians 5:1
C: Once free from one slave-master, do not look for another.
"For we are the true circumcision, who worship God in spirit, and glory in Christ Jesus, and put no confidence in the flesh. Though I myself have reason for confidence in the flesh also. If any other man thinks he has reason for confidence in the flesh, I have more: Circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew born of Hebrews; as to the law a Pharisee, as to zeal a persecutor of the church, as to righteousness under the law blameless. But whatever gain I had, I counted as loss for the sake of Christ." Philippians 3:3-7
C: If Paul no longer gloried in his ethnic background or his ancestry or the achievements of his "career," then why are we so foolish and obtuse to still be attempting the same?
"There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus. And if you are Christ's, then you are Abraham's offspring, heirs according to the promise." Galatians 3:28-29
C: Yes, the Greeks and Romans developed notions of rights for a class of privileged free citizens. But radical equality based on a common human dignity that encompasses all ethnicities, both slave and free, both male and female, is traceable to Christianity as a development of Judaism. That radical equality arises from the fact of being human, not from legal rights that a state deigns to grant.
