Question: Should Christians today be observing the feast days that were commanded in the Old Testament? Answer: It is indeed true that, as recorded in Leviticus 23, the Lord commanded that certain feast days and holy convocations should be kept.
There were also ordinances in the Old Testament in regard to drinking and also feast days. (See Leviticus 23.) Some of these feast days were called sabbaths. There were also ordinances in regard to new moons. Paul says, “Don’t let anybody judge you in regard to these things which are a shadow of things to come.”
