I see, and we are all equal in Christ's eyes? Circumcision or not? Sorry for the repetitive question, it's a inferiority complex. 1 Corinthians 7:18
Never apologize for seeking knowledge. The time you should apologize is when you have a question and don't ask it.
Deuteronomy 7:6-8 For you are a people holy to the Lord your God. The Lord your God has chosen you out of all the peoples on the face of the earth to be his people, his treasured possession. 7 The Lord did not set his affection on you and choose you because you were more numerous than other peoples, for you were the fewest of all peoples. 8 But it was because the Lord loved you and kept the oath he swore to your ancestors that he brought you out with a mighty hand and redeemed you from the land of slavery, from the power of Pharaoh king of Egypt.
1 Peter 2:9-10 But you are a chosen people, a royal priesthood, a holy nation, God’s special possession, that you may declare the praises of him who called you out of darkness into his wonderful light. 10 Once you were not a people, but now you are the people of God; once you had not received mercy, but now you have received mercy.
God did not chose the Jews because they were superior in any way or because they did something to earn it, so they are not superior to Gentiles, and through faith in Messiah Gentiles can also become part of God's chosen people, Israel (Romans 9:6-8, Ephesians 2:12-19). However, I think that God did make promises specifically to the Jews and has a different role for Jews than he does for Gentiles, just as an arm is not superior to a leg, but are both necessary parts of the same body.
Is this still relevant?
exodus 21:24
or has is been replaced with turn the other cheek?
How does a Christian justify revenge in regards to the new testament?
An eye for an eye was intended to be used as a guideline for judges to judge fairly in a way where a punishment corresponded to the crime, and in order to avoid escalation. It was not meant to be used to justify personal revenge as the Pharisees were doing. Whenever Jesus quoted from Scripture, he always preceded it by saying "it is written", but when he was quoting from the teachers of the Law, he preceded it by saying "you have heard that it was said". So in Matthew 5, Jesus was not sinning in violation of Deuteronomy 4:2 by making changes to God's Law or by adding his own brand new laws, but rather he was correcting what was wrongly being taught about God's Law and teaching how to correctly understand and obey it.
