Ephesians 2:11

So, you Gentiles by birth should remember what you once were. You are called "Uncircumcision" by those who are called "Circumcision" [i.e., the Jews], (which refers to a physical procedure performed by people).

Colossians 2:11

In [fellowship with] Him you people were also circumcised with a circumcision not performed by human beings, but performed by Christ, consisting of the removal of the body of [sinful] flesh.

1 Corinthians 12:2

You people know that when you were [still unconverted] Gentiles, you were led astray to [worship] lifeless idols, however you were led [i.e., wherever you turned, you were being led into idolatrous practices].

Ephesians 5:8

for you people were once darkness [i.e., when living in sin], but now you are light in [fellowship with] the Lord. [So], live like people who belong to light [i.e., who live godly lives],

Colossians 2:13

And when you were [spiritually] dead because of your sins and your lack of being physically circumcised [Note: This refers to their having been unconverted Gentiles and therefore outside of a relationship with God], God made you alive [again] together with Christ, having forgiven us for all of our sins.

Romans 2:28-29

For that person is not a Jew who is one [merely] on the outside. And circumcision is not [merely] an outward physical ordinance.

1 Corinthians 6:11

And some of you have practiced such things, but you were washed [i.e., from your sins. See Acts 22:16]; you were dedicated [i.e., set apart for God's service]; you were made right with God in the name [i.e., by the authority] of the Lord Jesus Christ, and by the Holy Spirit of our God.

Galatians 2:15

Although we are Jews by natural birth, and not sinful Gentiles [who do not have a relationship with God],

Galatians 4:8-9

At that time, when you did not know God [as your Father], you were in bondage to those who were, by nature, not really gods at all.

Galatians 6:12

Those who attempt to make a good impression by trying to force you to be circumcised really want only to avoid being persecuted for their commitment to Christ.

Philippians 3:3

For we [Christians] are the [true] circumcision [i.e., the real "Jews" in God's eyes. See Rom. 2:28-29]. We worship by means of God's Holy Spirit [i.e., are empowered and motivated by the Holy Spirit], and boast in [the person and work of] Christ Jesus, and [we] place no confidence in the flesh [i.e., in any outward ritual or status for salvation].

Colossians 1:21

And though you were once estranged [from God] and were enemies [of His] in your mind because of your evil deeds,

Colossians 3:11

[In this state] there cannot be [such distinctions as] Greek [i.e., Gentile] and Jew; circumcised people and non-circumcised people; barbarian and Scythian [Note: These last two words refer to foreigners whose language was unintelligible and who were uncivilized heathens], or slave and free person; but Christ is all [that is important] and [He is] in all [of His people].

Romans 2:29
But the [true] Jew is the person who is one on the inside, and [his] circumcision is a heart condition, [produced] by the Holy Spirit and not by the written law of Moses. [Note: Some translate "Spirit" here as "spirit" and make it simply an amplification of "heart"]. This person receives his praise from God and not [merely] from people.
