Hosea 2:11. I will also cause all her mirth to cease, her feast days, her New Moons, her Sabbaths all her appointed feasts.
The "her" here is Israel. I read this as the Feasts and Sabbaths are SUSPENDED until the Return of Messiah. This is in conjuction with the absence of the Temple where the corresponding prescribed sacrifices even in sabbath are non-existent today.
In other words although we keep tab of the appointed times or moedim, however we celebrate or memorialize the Feasts, they are not the biblical Feasts itself but made up human renditions.
In my desire to keep Torah, I want to keep the Feasts. But how do we keep the Feasts according to Scripture without the sacrifices?
Today, most Messianics and Nazarenes are keeping the Feasts according to Pharisee/Rabbinate traditions and times. Although the Karaites try to use the harvest and moon times, they too do not have the proper sacrifices.
In general, how to we keep Torah without the Temple?
Hosea 2:11 in context is speaking of the House of Israel as distinct from the House of Judah... I do not see how you read Rabbis of the House of Judah figure into Hosea 2:11. Rabbinic Judaism did not arise until many centuries after Ephraim separated from Judah. This has much more to do with Ephraim mixing paganism into their faith.
Judah is still lost for the most part. do not follow Judah. Follow Israel. Israel is not yet restored, but the truth of Israel is necessary. Judah still hangs on to their rabbinic falsehoods.
Methinks that the only reason for feasts to cease is during a time of captivity / chastisement of YHWH, in which the ability to actually keep the appointed times is significantly compromised.
