Hello Peter. I hope you had a blessed weekend.
I just want to make a couple of brief comments to your reply.
Let me be clear; I never stated that the festivals were abolished. What I said was that these were mandated by God to ISRAEL (Jews) as a way to remember the great and mighty acts of mercy and deliverance. My point is that although they are permissible, they are not mandated for theGentile believers. As for the ceremonial practices, I was thinking of the procedures of washing, cooking, dressing, etc. and things that pertain to the Leviticus order of worship related to the sacrifices. The fact that Levites as a clan do not exist is evident that these things cannot be practiced. As a matter of fact, no modern Jew can determine from which tribe they descend since the census records have long since been destroyed.
The key to understanding the issue of observance of Jewish Law is context. When rightly applied, the rules of hermeneutics (context, rules of language, exegesis, etc.) makes this issue quite clear as was explained in Acts 15. Nevertheless, there were those who insisted that Jewish converts adopt and maintain the same regulations as Jews. This created much confusion for the Gentile believers in Antioch as well as the Galatians and Colossians. This is also why Paul stressed the application of moral precepts and a life transformed by the "renewing of the mind (Ro 12:1-2).
The personal example that Paul cites in Philippians when examined in context has nothing to do with following Jewish regulations, but rather a lifestyle of sacrifice and love. All of the instructions provided in each of his letters pertain to a lifestyle that results from a transformation of the heart by a personal encounter with the living Savior and explicitly charges people to NOT become entangled in legalism as a means of righteousness.
I am not sure where you see a reference in 1 Cor. 5 pertaining to the Passover. The entire chapter is dedicated as a rebuke to immorality (another emphasis on moral precepts). In verse 7 there is a mention of Christ being our Passover as THE sacrifice. This is in context of not allowing sin a foothold in our lives as a means of leaven. As for the feast in verse 8; we always remember the Passover as it proceeds Easter; however, here he appears to be speaking figuratively regarding the attitudes of our heart regarding the Lord's Supper which we should be practicing each time we meet as they did at that time. Again, the emphasis here is repentance "from morality and wickedness" to a heart of "sincerity and truth."
As for the prophesies of Zechariah: the 14th chapter appears to pertain to the millennial reign of Christ and those who rise up against Israel during the rule of the anti-Christ. These will be those have "rejected the truth so as to be saved." In other words, they are unbelievers; rejecter's of Divine Truth. How the Lord chooses to deal with them at that time should not be construed as a patter for our lives now.
As for Isaiah 66:23; yes every knee will bow and every tongue will confess that Jesus Christ is Lord. This is a certainty.
It appears that we are not going to find much common ground on this issue Peter. Nevertheless, I look forward to having fellowship with you as we walk together.
Blessings to you Peter
If you're a Messianic and your primary congregation is a Messianic congregation then visiting a church won't hurt you. The Messianic sphere of influence will neutralize the poisonous teachings you hear at church and inoculate you to the subtle social rejection you'll receive from Christians (no matter what they say, they won't really accept someone that they think is a legalistic Pharisee).
But if you're Messianic and you only go to a church...be prepared for a slow, tortuous spiritual death. One cannot live without true fellowship. And a Messianic can't live without hearing the Teaching.
