Absolutely incorrect! The church at Colossae consisted of newly converted, previously pagan, Greeks. They had no inkling of God's holy days, festivals and Sabbaths prior to their conversion. Paul is instructing them in the observance of the ordinances....."Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath Day."
Why in the world would Paul waste his time explaining something to these folks if he then wanted them to ignore it?
Explain Matthew 28:1 to me.
1) Obviously he was referring to Jewish customs. You think the Greeks knew nothing about the Jews? 2) At dawn on the day after the Sabbath, Mary Magdalem and the other Mary came near to contemplate the tomb. So?
