The answer is right there in Acts 15
For the law of Moses has been preached in every city from the earliest times and is read in the synagogues on every Sabbath.”
Gentile believers were not instructed to go to Sunday church and learn the law of Moses but to go to the synagogues every Sabbath and learn the law of Moses. Now this was after the death, burial and resurrection of Jesus.
Someone forgot the laws were nailed to the cross?
Romans 4:
Release from the Law
…3So then, if she is joined to another man while her husband is still alive, she is called an adulteress; but if her husband dies, she is free from that law and is not an adulteress, even if she marries another man.4Therefore, my brothers, you also died to the Lawthrough the body of Christ, that you might belong to another, to Him who was raised from the dead, in order that we might bear fruit to God. 5For when we lived according to the flesh, the sinful passions aroused by the Law were at work in our bodies, bearing fruit for death.…
LAW (not plural)
Deuteronomy 24:
1If a man marries a woman who becomes displeasing to him because he finds something indecent about her, and he writes her a certificate of divorce, gives it to her and sends her from his house, 2and if after she leaves his house she becomes the wife of another man, 3and her second husband dislikes her and writes her a certificate of divorce, gives it to her and sends her from his house, or if he dies, 4then her first husband, who divorced her, is not allowed to marry her again after she has been defiled. That would be detestable in the eyes of the Lord. Do not bring sin upon the land the Lord your God is giving you as an inheritance.
Jeremiah 3:
8I gave faithless Israel her certificate of divorce and sent her away because of all her adulteries. Yet I saw that her unfaithful sister Judah had no fear; she also went out and committed adultery.
Jeremiah 3:
1“If a man divorces his wifeand she leaves him and marries another man,should he return to her again?Would not the land be completely defiled?But you have lived as a prostitute with many lovers—would you now return to me?”
Jeremiah 3:
11The Lord said to me, “Faithless Israel is more righteous than unfaithful Judah. 12Go, proclaim this message toward the north:“ ‘Return, faithless Israel,’ declares the Lord,
‘I will frown on you no longer,
for I am faithful,’ declares the Lord,
‘I will not be angry forever.
13Only acknowledge your guilt—
you have rebelled against the Lord your God,
you have scattered your favors to foreign gods
under every spreading tree,
and have not obeyed me,’ ”
Jesus came as "God with us".
Jesus had to die and ressurect in order for the House of Israel to be able to return to God without God violating His own law (Deuteronomy 24)
Matthew 15:24 But he answered and said, I am not sent but unto the lost sheep of the house of Israel.
John 3:16 For God so loved the world that He gave His only begotten son, that whosoever believes in Him, should not perish but have everlasting life.
God's invite in the time of ancient Israel has always been open to non-Israelites.
God says He does not change.
Jesus did not come to start a new religion that excludes Israel.
Paul did not come to start a new religion that excludes Israel.
The division of the church and Israel is a lie and many claim this lie to be their truth, thus those with eyes to see and ears to here will fully understand the gospel of the kingdom, the rules of the kingdom, and the king of kings and Lord of lords who had to die for all are sinners and their is no salvation available apart from believing on Jesus Christ, and also dying to our old natures that we may live in newness of life.
We are adopted and grafted into Israel. The new covenant is not for Gentiles.
Jeremiah 31:31“The days are coming,” declares the Lord,
“when I will make a new covenant
with the people of Israel
and with the people of Judah.
32It will not be like the covenant
I made with their ancestors
when I took them by the hand
to lead them out of Egypt,
because they broke my covenant,
though I was a husband to[SUP]d[/SUP] them,[SUP]e[/SUP] ”
declares the Lord.
33“This is the covenant I will make with the people of Israel
after that time,” declares the Lord.
“I will put my law in their minds
and write it on their hearts.
I will be their God,
and they will be my people.
34No longer will they teach their neighbor,
or say to one another, ‘Know the Lord,’
because they will all know me,
from the least of them to the greatest,”
Hebrews 8:The New Covenant
7For if that first covenant had been without fault, no place would have been sought for a second. 8Butwhen God found fault with the people, He said:“Behold, the days are coming, says the Lord, when I will make a new covenant with the house of Israel andwith the house of Judah. 9It will not be like the covenant I made with their fathers when I took them by the hand to lead them out of the land of Egypt, because they did not abide by My covenant, and I disregarded them, says the Lord.…
Deuteronomy 29:The Covenant in Moab
…13in order that He may establish you today as His people and that He may be your God, just as He spoke to you and as He swore to your fathers, to Abraham, Isaac, and Jacob. 14"Now not with you alone am I making this covenant and this oath, 15but both with those who stand here with us today in the presence of the LORD our God and with those who are not with us here today…
Hebrews 10:Christ's Perfect Sacrifice
…15The Holy Spirit also testifies to us about this. First He says: 16“This is the covenant I will make with themafter those days, says the Lord. I will put My Laws intheir hearts and inscribe them on their minds.” 17Then he adds: “Their sins and lawless acts I will remember no more.”…
Ezekiel 20:Rebellion in Egypt
…10"So I took them out of the land of Egypt and brought them into the wilderness. 11"I gave them My statutes and informed them of My ordinances, by which, if a man observes them, he will live. 12"Also I gave them My sabbaths to be a sign between Me and them, that they might know that I am the LORD who sanctifies them.…
What? Sabbath is a sign between God and Israel so we know it is the LORD who sanctifies Israel?
Are you saved by grace and yet cannot love God the way He says He wants? Because He first loved me, I desire Him and His ways which we are instructed in Torah, our blueprint to holy and set apart living.
I choose to believe on Jesus and His redemptive work. Praising YHWH for His abundant GRACE!
If you are another one who believes that in order to be a Christian one must become a Jew, all power to you.
That is NOT the thrust of Acts, or Romans, or Galatians, or Hebrews.
I bet you must have all the pages of Hebrews glued together!
All the issues of how to deal with Gentile believers were hammered out 2000 years ago.
The Judaizers were put in their place.
The Council of Jerusalem emphatically affirmed that Gentile believers were not bound to the dictates of Levitical law.
The book of Hebrews is an amazing treatise that deals with Jewish believers who were under pressure to abandon the New covenant and return to the Law.
The writer of Hebrews brilliantly outlines how the New Covenant is better in every way compared where they had come from.
I will only say this: if you place yourself under the Law you are bound on EVERY point of it. Fall on one point and you fail on every point. Be sure of this - the Law has not passed away. Every jot and tittle of it as laid out in the Mosaic books has to be obeyed if you are under the Law. There is no abbreviated version of it in operation now if you are under the Law. Remember - every jot and tittle!
The Law cannot save.
One can only be saved by grace through faith in the sacrifice of Christ Jesus on the cross. There is no other combination or permutation by which man can be saved.
The blood sacrifice of Christ Jesus on the cross fulfilled every righteous requirement that the Law makes on us.
If we accept this sacrifice by grace through faith, then, as believers, we are not subject to the demands of the Law.
There are no longer dietary restrictions, days and feasts, blood sacrifices to be made. These are done away with.
In its place is a higher calling based on the love we have for Christ Jesus.
The genesis of that love is very simple.
We love Him because He first loved us.
That higher calling cannot be subject to the Law because the Law is all about minimum requirements and penalties for transgression.
What we are called to as children of God cannot be legislated; instead it can only unfold as a consequence of us loving and following God.
To the casual onlooker we would appear to be 'law-abiding' citizens, but, in fact, we are not doing the minimum required to 'stay out of trouble', but rather the maximum of what God has called us to at that time.
So often, the response to this is some kind of accusation that we can then do exactly as we please without check or bound. However, Christians are not lawless reprobates. We wish to please God instead. The law can be summed up as two important principles: Love the Lord your God, and, love your neighbour as yourself. In this sense the Holy Spirit will guide us.
Furthermore, if we do sin, our salvation is not compromised. Our position as children of God is secure. The sin does however impede our love relationship with God. In such situations the approach is to confess our sin before God, repent, and move on, back to what God has called us to.
