The leaven here is adding a little law.
3 I testify again to every man that receiveth circumcision, that he is a debtor to do the whole (OT) law.
The following are NT verses to clarify Christians relationship to the laws of God as given in the Old Testament:
(OT is used and abbreviated from the words, "OLD TESTAMENT")
For as many as are of the works of the law are under the curse:
for it is written, Cursed is every one that continues not in all things which are written
in the book of the (OT) law to do them.
5:18 But if ye be led of the Spirit, ye are not under the (OT) law.
Romans 7:6 But now we have been discharged from the (OT) law, having died to that wherein we were held; so that we serve in newness of the spirit, and not in oldness of the (OT) letter.
Col. 2:20 Wherefore if ye be dead with Christ from the rudiments of the world, why, as though living in the world, are ye subject to (the OT LAW) ordinances?
14 Blotting out the handwriting of ordinances (contained in the law)
that was against us, which was contrary to us,
and took it (the law) out of the way, (OUT of the way.)
nailing it (the law) to his cross;
7:12 - For the priesthood being changed, there is made of necessity a change also of the law.
:8 For finding fault with them, he saith, Behold, the days come, saith the Lord,
when I will make a new covenant with the house of Israel and with the house of Judah:
:9 Not according to the covenant (contained in the law) that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt;
Now that (the OT law) which decayeth and waxeth old is ready to vanish away.
Why was it getting ready to to vanish away?
At the time the NT scriptures were written, the nation of Israel, the temple, and the OT priesthood still stood and outwardly functioned. But Christ had already pronounced Jerusalem and the House of God there "desolate" and the Romans would come and wipe national Israel and the temple, off the map in 70 ad.
When that took place, it became IMPOSSIBLE to observe even a form of the OT law that required a temple, priesthood, sacrifices, feasts, tithing, and many other ordinances specifically required by God's OT laws, statutes, ordinances, and commands.
And so we read regarding the priesthood and sacrifices under the law:
9:9 Which was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience;
:10 Which stood only in meats and drinks, and divers washings, and carnal ordinances,
imposed on them until the time of reformation.
17 Which are a shadow of things to come; but the body is of Christ. "
21 (Touch not; taste not; handle not;
22 Which all are to perish with the using;) after the commandments and doctrines of men?
23 Which things have indeed a show of wisdom in (self-) will worship
Acts 21:20 And when they heard it, they glorified the Lord, and said unto him, Thou seest, brother, how many thousands of Jews there are which believe; and they are all zealous of the(OT) law:
21 And they are informed of thee, that thou teachest all the Jews which are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children, neither to walk after the customs.
22 What is it therefore? the multitude must needs come together: for they will hear that thou art come.
23 Do therefore this that we say to thee: We have four men which have a vow on them;
24 Them take, and purify thyself with them, and be at charges with them, that they may shave their heads: and all may know that those things, whereof they were informed concerning thee, are nothing; but that thou thyself also walkest orderly, and keepest the (OT) law.
(which was in the process of “decaying” and “vanishing away” as the Jewish temple and nation had been “desolated” by Christ, but still existed at the time scripture was written)
25 As touching the Gentiles which believe, we have written and concluded that they observe no such thing (the OT laws) , save only that they keep themselves from things offered to idols, and from blood, and from strangled, and from fornication.
He told us!
1st Corinthians 9:19 For though I was free from all men, I brought myself under bondage to all, that I might gain the more.
Here it is:
to them that are under the law, as under the law,
not being myself under the law, that I might gain them that are under the law;
15 We who are Jews by nature, and not sinners of the Gentiles,
16 Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified
Stand fast therefore in the liberty wherewith Christ hath made us free,
and be not entangled again with the yoke of bondage. (to the law)
Are ye so foolish? having begun in the Spirit,
are ye now made perfect by the flesh? ("perfect" meaning complete,in works of the flesh, by keeping the OT law the Lord abolished)
how turn ye again to the weak and beggarly elements, (the OT law)
whereunto ye desire again to be in bondage? (the OT law)
But if the ministration of death (the OT law), written and engraven in stones (the law), was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away: 8 How shall not the ministration of the spirit be rather glorious?
9 For if the ministration of condemnation (th OT law) be glory, much more doth the ministration of righteousness exceed in glory.
10 For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth. 11 For if that which is done away (the law) was glorious, much more that which remaineth (NT faith) is glorious.
12 Seeing then that we have such hope, we use great plainness of speech:
13 And not as Moses, which put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished: (the OT law)
14 But their minds were blinded: for until this day remaineth the same vail (the OT law)
untaken away in the reading of the old testament; which vail is done away in Christ. (By observing an OT law we veil the face of Christ)
Do you really want to be a debtor to do the *WHOLE law, as the law itself commanded?
5:9 A little leaven (from OT law) leaveneth the whole lump.
3:10 For as many as are of the works of the (OT law) are under the curse:
for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them.
Just a little law such as tithing/sabbath/ dietary /feasts, etc., leavens, it vails, it makes Christ no effect, it brings us under the curse, etc....
6 Concerning zeal, persecuting the church; touching the righteousness which is in the law, blameless.
7 But what things were gain to me (the righteousness of the OT law), those I counted loss for Christ.
Why would he count the OT law “loss”?
8 Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ,
9 And be found in him, not having mine own righteousness, which is of the law,
but that which is through the faith of Christ, (is) the righteousness which is of God by faith
Blotting out the handwriting of ordinances that was against us (in the law),
which was contrary to us, and took it out of the way, nailing it to his cross;
15 And having spoiled principalities and powers, he made a show of them openly, triumphing over them in it.
16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days (as given in the law):
17 Which are a shadow of things to come; but the body is of Christ.
When Christ, the LIGHT comes, the shadow goes away.
7:22 By so much was Jesus made a surety of a better testament. (the NEW one)
8:6 But now hath he obtained a more excellent ministry,
by how much also he is the mediator of a better covenant, which was established upon better promises.
For if that first covenant (the OT law) had been faultless, then should no place have been sought for the second.
8 For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:
9 Not according to the covenant (the law) that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt (the law) ;
because they continued not in my (OT) covenant, and I regarded them not, saith the Lord. 10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
11 And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest.
12 For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
13 In that he saith, A new covenant, he hath made the first old (the law) .
Now that which decayeth and waxeth old (the law) is ready to vanish away.
5 For we through the Spirit wait for the hope of righteousness by faith.
6 For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.
If any part of the law does not justify us, and was: Having abolished in his flesh the enmity, even the law of commandments contained in ordinances," then
WHY CONTINUE DOING THAT WHICH WAS ABOLISHED IN HIS FLESH,
which will cause you to be “fallen from grace”, brings you into a “yoke of bondage”, by which “shall NO flesh be justified”, and brings you “under a curse” for not “doing ALL things that are written in the law to do them”?
addendum for those that may doubt me yet:
If you have even a FLICKER of doubt in your ability to keep, observe, and do ALL that is written in the law, please read carefully the following:
Definition: all, the whole all, the whole of, any, each, every, anything, totality, everything
-No splitting hairs on this one, God meant "all" when He commanded "all".
And the penalty for breaking and not doing "all" the way He gave "all" in the laws, staututes, commandments, and ordinances" was often death and being "cut off" from Israel.
