BOTH OLD AND NEW TESTAMENTS MAKE ALL THE DOCTRINES OF THE BIBLE UNCHANGEABLE EXCEPT AS NECESSITATED BY THE BODY OF JESUS (Colossians 2:16) OR BY HIS OWN SPOKEN ADJUSTMENTS. Note that Colossians 2:16 MAKES OBSOLETE OR CANCELS all that is mentioned in that verse. However, we must understand that the verse speaks of food (meat) OFFERINGS and drink OFFERINGS and not regular food and regular drink. Besides, there is no forbiddance on drinking in the Jewish Bible.
Also, the plural sabbaths, according to the Greek manuscripts, that were introduced by Moses are obsolete not the seventh day Sabbath, day of Jesus who, hence, is YHWH according to the ownership of the seventh day in Mark 12:8 and Isaiah 58:13, the day which the Israelites were called to remember to keep. The body of Jesus cannot be the shadow of the seventh day Sabbath as it is erroneously being taught by the Antichrist and his agents.
Again, the seventh day Sabbath cannot be obsolete based on the immutability clauses of the doctrines of the Jewish Bible, as Jesus also declares it in the New Testament.
What to hold to and and what to discard from the Scriptures?
The New Testament validates Eternal Faith, Eternal Behavior, and the fulfilment of the shadows of YHWH God to become flesh to be known as Yhoshua (Jesus). Colossians 2:16, John 1, Romans 10:9-11, Luke 1:35, 2:11, John 3:16.
Determine whether or not your biblical questions pertain to one of the three themes which the Bible covers. Anything pertaining to the shadows of things pointing to death of Jesus is no longer biding to be kept because it also requires the erected Temple and the priesthood to resume the rites in Israel and within the Temple.
The Genesis hallowed sabbath day of YHWH or of Jesus has remained in force because it was instituted at the creation of time as the day which belongs to Jesus. The last supper was instituted as a remembrance. Love one another was added as a new commandment. So, in Moses, all the old feasts or festivals pointing to the redemptive works of YHWH God, which were tied to Israel and the erected Temple, and the local judgments calling for the death penalty are no longer valid.
Behavioral rules can never be adjusted or changed in any generation. Faith in Jesus, the Only God Saviour (YHWH), gives eternal life.
Again, keeping in mind all the preceding summary, anyone can find the answer to their own biblical questions.
