2 Corinthians 5:17
Therefore, if any person is in [fellowship with] Christ, he is a new person. His old ways have passed away; now his ways have become new.
For [certain] false brothers, who were secretly brought in to observe us practicing our liberty in Christ Jesus [i.e., by not having Titus circumcised], attempted to place us [back] under the bondage [of Mosaic law keeping].
But now that you have come to know God [as your Father], or rather, to be known by Him [as His children], how can you turn back again to the weak, cheap, elementary teachings [of the law of Moses], to which you [seem to] desire to become enslaved?
Christ set us free [from condemnation under the law of Moses], so we could stay free! Remain where you are then, and do not get tangled up again in the enslaving harness [of the law of Moses].
For not even those who practice circumcision comply with [the requirements of] the law of Moses, yet they want you to be circumcised so they can take credit for this physical evidence [of your compliance with the law of Moses].
[I was] circumcised eight days after I was born; [I am] from the nation of Israelites; from the tribe of Benjamin and of Hebrew ancestry [i.e., an outstanding Hebrew]. As far as the law of Moses is concerned, [I am] a Pharisee [i.e., a strict sect of the Jewish religion].
He is not holding on [firmly] to the head [i.e., Christ, the head of the church], from whom the entire body, being nourished and supported by its ligaments and joints, is caused to grow in size by God.
1 Timothy 4:8
For physical training is useful to some extent [or, "for a short time"], but living godly is useful in every way, for it promises benefits [not only] for the present life, but [also] for the life to come.
For God found fault with the Israelites [or, possibly with the first Agreement], saying [Jer. 31:31ff], "Look, the Lord says, the time will come when I will make a New Agreement with the people of Israel and with the people of Judah.
Do not continue to be swept off your course by all kinds of strange teachings. For it is good for your hearts to be strengthened by God's unearned favor [upon you] and not by [keeping regulations about] foods, which do not benefit those who observe them.
Then the One who is seated on the throne [i.e., Christ, or God] said, "Listen, I am making everything new!" Then He said, "Write [this], because these words are trustworthy and true."
