Please explain why you observe Old Testament days of worship? Paul seems to say that these days are no longer important, like Galatians 4:10 and Colossians 2:16.
Our Savior an 
d every Apostle and disciple in the New Testament kept the Feast days commanded by Yahweh for His people Israel. Yahshua kept the Passover and Feast of Unleavened Bread with His disciples before He died, Matthew 26:17. He became the Passover Lamb sacrificed for the sins of the world. He kept the other Feasts like Tabernacles as well, Luke 2:42. Surprising to some, the champion of Christians, the Apostle Paul, kept these Feast days as well, as is clear from many passages in the New Testament. In Acts 18:21 he was resolute: “I must by all means keep this feast that comes to Jerusalem.”
All the big events in Scripture occurred or will occur at a Feast times. At Passover was the release of Israel and our Savior’s atoning death; His resurrection occurred during the Feast of Unleavened Bread. On Pentecost both the law and Holy Spirit were given. Yahshua will likely return at Trumpets. Tabernacles and Last Great Day represent the establishing of the Kingdom.
Galatians 4:10 speaks of pagan observances, not Yahweh’s appointed times. Colossians 2:16 is an admonishment not to let outsiders judge the believer when it comes to Yahweh’s special days.

You do not turn again to something that is new so it is obviously talking about them trying to return to their old paganism. Colossians 2:16 is even more telling. First you have to understand that these new assemblies were being attacked not only by the “Jews” but by… Read more »
