I would like to look at the holy days that christ kept and why he did not keep the holidays. In Matt 5:17 he starts his ministry with this clarification that he was not changing one jot or tittle of the law. Most people think that because he denounce the tradition of men added as a millstone to the Israelites that he did away with the law. Not so he magnified the law Matt 5:27 Adultery in the heart was the same as the physical act .  Matt 5:21 Murder and hate carry the same sin and penalty, death. I encourage you to read Matt.5  in light of what I have just wrote. Mark
