No, the feast days, new moons, and Sabbaths were, according to Paul, "a shadow of the things to come".
As a point of order, Paul says the feast days, new moons, and Sabbaths ARE shadows of things to come...
And the conventional Christian view of Paul's letter to the Colossians falls apart with just a little consideration - Colossians are pagans of Galatia... Generally practitioners of the Babylonian Mysteries (Astrology). How would it be that Paul is warning them *not* to go back to Judaism? They would not have been practicing Judaism in the first place, at least not by and large...
Equally problematic, 'new moons' are not that important in Judaism... One feast alone is tied to a new moon (Feast of Trumpets) - The rest of the feasts are tied to the full moon. So why the peculiar emphasis on new moons? But, new moons are part and parcel of astrology, even to this day.
And reading further on Col2 we find Paul is speaking of 'rudiments of the world' (20) and 'ordinances [...] after the doctrines and commandments of men' (20-22)
How can that be the eternal Torah, which is the ordinances, doctrine, and commandments of YHWH?
No, standard Christian interpretation of this passage leaves much to be desired.
Very good points.........All!
