They are not Jewish feasts, they are God's feasts:
Lev 23:4 These [are] the feasts of the LORD, [even] holy convocations, which ye shall proclaim in their seasons.
And since God tells us they're his feasts, and Christ kept them as an example, then there's no doubt that the first Christians honored God by observing his feasts.
Do you have any examples that you could sight for me in the NT?
Also, what would your thoughts be on circumcision and dietary restrictions as practices by the Jews?
No they are feasts that God gave TO THE JEWS as a sign, Gentiles were NEVER ordered or never was it suggested that they are are to celebrate them .
Lev 23:4 These [are] the feasts of the LORD, [even] holy convocations, which ye shall proclaim in their seasons.
Doug this was written to the jews..
And since God tells us they're his feasts, and Christ kept them as an example, then there's no doubt that the first Christians honored God by observing his feasts.
Christ kept them BECAUSE HE WAS A JEW. Jesus was without sin, failing to observe the laws would have been sin. I will remind you that the Gospels were written under the Old Testament. The NEW Testament does not begin until the death of Christ.
What did he say at the last supper to the men that would build his church?
Did he say "celebrate every Passover?" or did he say 'DO this in remembrance of me'? He mover the celebration of Passover AWAY from the original Jewish holiday and instead celebrated the "Lords table" ..a command of the New Testament
When the question was asked about whether or not the Gentiles would be placed under the law they held a council . The Jerusalem Council was called specifically to resolve putting the converts under the law. The new church was at first seen as a sect of Judaism so the question was, were the gentiles now Jews and under Jewish law .The matter is discussed in Acts 15. Here is their authoritative decree concerning what Gentile converts to Christianity were obligated to do:
23 They sent this letter with them: From the apostles and elders, your brothers, to the Gentile brothers and sisters in Antioch, Syria, and Cilicia, greetings!
24 Since we have heard that some have gone out from among us with no orders from us and have confused you, upsetting your minds by what they said,
25 we have unanimously decided to choose men to send to you along with our dear friends Barnabas and Paul,
26 who have risked their lives for the name of our Lord Jesus Christ. 27 Therefore we are sending Judas and Silas who will tell you these things themselves in person.
28 For it seemed best to the Holy Spirit and to us not to place any greater burden on you than these necessary rules:
29 that you abstain from meat that has been sacrificed to idols and from blood and from what has been strangled and from sexual immorality. If you keep yourselves from doing these things, you will do well. Farewell.
Galatians is very clear on this matter Doug. Paul explains because of God's grace, Gentiles who came to salvation were not required to keep the feasts. They were expected to give up idolatry and obey the seven Noahide laws PERIOD .In Philippians chapter 3 Paul warns the saints in Philippi about Jewish legalizers. In 1 Timothy chapter 1 Paul warns Timothy and the Ephesian saints about those would-be teachers of the law, who were most surely Jews (1:3-11). In 1 Timothy 4 Paul warns about the "doctrines of demons," which involves the prohibition against eating certain foods (4:3). In Titus 1:14 Paul warns about "Jewish myths." I think one must say that the Judaisers are still with us today, and we must beware of falling into their error.
There is nothing here at all requiring Gentile believers to observe Jewish feasts. If this were a requirement, this would have been the place to say so.
Your church places you under Jewish legalism , makes salvation a work of the flesh and not one of grace and mercy .
