Col. 2:17a shadow of the things to come. The old covenant observances pointed to a future reality that was fulfilled in the Lord Jesus Christ (cf.Heb. 10:1). Hence, Christians are no longer under the Mosaic covenant (cf.Rom. 6:14–15; 7:1–6;2 Cor. 3:4–18;Gal. 3:15–4:7). Christians are no longer obligated to observe OT dietary laws (“food and drink”) or festivals, holidays, and special days (“a festival … new moon … Sabbath,”Col. 2:16), for what these things foreshadowed has been fulfilled in Christ. It is debated whether the Sabbaths in question included the regular seventh-day rest of the fourth commandment, or were only the special Sabbaths of the Jewish festal calendar.
