Col 2:20 Therefore, if you died with Christ from the basic principles of the world, why, as though living in the world, do you subject yourselves to regulations—
The biblical holy days of the Lord are not basic priniciples of the "World". They are the days commanded by the Lord in sacred scripture.
Col 2:21 "Do not touch, do not taste, do not handle,"
Col 2:22 which all concern things which perish with the using—according to the commandments and doctrines of men?
The biblical holy days of Jesus Christ are not "commandments and doctrines of men" but are holy days created and instituted by Jesus Christ.
The view you're repeating of Colossians 2 is an old one that attempts to justify not observing the Lords' holy days.
Oh, I struck a nerve.
Easter is Biblical or its a tradition of men.
Where in the Bible is it commanded we celebrate Easter?
