Christians do not celebrate pagan feasts.....and neither do I. So you are assuming that which isn’t so....I do not live by Jewish Law...which was given to the Jewish People..and which they could not satisfy...no man can.
Again... God knew man would fail and thus sent His son to have victory over what man could not do himself....Jesus fulfilled ALL the requirements of the Jewish Law...there is no mistake about that..... To say otherwise means His life, death, burial and resurrection did not satisfy Gods redemption for man.....and thus man has no hope... for if you sin in one of the least of the commandments you are guilty of them all...
We are fully redeemed by the righteous fullfillment of the Law in Christ.... or we are doomed...there is no middle line.

I took your remark to mean that you celebrate Christmas, and Easter, which are definitely pagan feasts that have no relationship to Yeshua whatsoever.
Yeshua fulfilled the spring feasts, and the intermediate fulfillment of Sukkot. He also fulfilled the prophecies of the Lamb of God that paid the sins of the world.
Torah is not fulfillable, since it is just a set of cammandments. Yeshua stated that Torah is to be unchanged until all things are fulfilled and his enemies are made his footstool. That is yet to happen, as Satan prwesently rules the world, and Yeshua’s millenial reign has yet to begin. Also the First Resurrection is yet to come, and will happen at the last trump of Yom Teruah as Paul pointed out in 1Thessalonians.
The rest of your post creates your own Bible, and is thus unaddressable.
