Modern Christianity (those whom focus primarily on the New Testament, neglecting the 10 commandments) typically follow a certain set of holidays, with the two most prominent being Christmas, and Easter. What most don't realize is that there were heretics in the church post-Christ whom, just as Israel had done so many times in the past, went their separate way; leading people astray with the notion that you do not need to follow the 10 commandments anymore, as there is a New Covenant of which all may be saved.
The truth is that all may be saved based on the New Covenant, however as Christ himself indicated, he didn't come to abolish the law, but to fulfill it (Matthew (Matityah) 5:17-20). Some might use the fact that Blessed are the Peacemakers, and insight this as "because you don't believe what I believe, which makes me mad, you're not a peacemaker", neglecting the fact that Christ himself was no such peacemaker in this accord. Christ did not please men, nor women, which is why he paid the ultimate price for our sins with his life. He preached the gospel, and how we must follow it, being the "way, the truth, and the light", however most believe based on John (Yochanan) 3:16 that merely believing grants you salvation.
What most of these types of Christians neglect is simple truths: Christ was a Jew, and in fact, the king of the Jews. Christianity historical has been exceptionally anti-Semitic, neglecting that Christ was the example to Jews and Gentiles alike as to how to properly follow those 10 commandments. Matthew (Matityah) 15 shows clearly that most are concerned with the washing of their hands, however it's not what goes into the mouth that defiles a man, but what comes out of the mouth of a man that defiles a man (just as 5:17-20 indicates, preaching against the 10 commandments.). The other argument would be that you need to "Love thy neighbor as thyself"; however they neglect the purpose of that statement. To put it into context, if you were to see a relative with a knife in their hand with full intent on injuring themselves, or another person, would you ignore them completely and let them follow their own way, or would you try to intervene?
The other point being, and this is a key factor in understanding, that a person need to remove the mote from their own eye prior to trying to remove it from their brothers. That's to say quite simply if I am a liar, I shouldn't go around telling other people not to lie. If I'm a murderer, the same thing applies. Stealing, coveting, idolatry...just to name a few more of those 10 commandments; these are the types that are hypocrites in the eyes of Christ, of which he was rebuking and ultimately put to death for speaking against.
One only need read a little further in John (Yochanan) to chapter 4, verse 22 to see clearly that "salvation is of the Jews (Yehuda)."
With this in mind, James 2:10 comes into play, as one whom breaks one breaks them all. A teacher, in biblical terms, is the ultimate goal of a true Christian; having a pure heart and being able to guide others into the truth. We'll discuss the 5 fold ministry later, however in short, Easter is idol worship to Ishtar, the Babylonian Goddess (aka Semiramis, the wife of Nimrod). Her husband was the Sun God Baal (Nimrod, whom was replaced by Tammuz, his son, considered to be the reincarnation of Nimrod aka Baal). Christmas and Easter are pagan traditions stemming from Babylonian times in worship to real people whom assumed the identities of deities, however were no such thing. Art history clearly indicates this as depictions of Tammuz (the reincarnation of Baal) and Semiramis (Ishtar) replaced images of Christ and Mary.
