If there is a mistake in the list below, please correct me in the comments. If you have additional un-Scriptural Christian traditions you'd like to add to this list, please let me know in the comments.
Finally, I suspect some may be offended by this, because most of us actually practice some of these. The purpose isn't to offend, but is only to shed light on what is man-made versus what God has commanded. It's up to you to figure what to do from there. Please understand I'm not saying all these things are evil; I'm simply stating what has Scripture support and what does not. I hope this helps you all align your theology accordingly!

- Nowhere in Scripture does it say God's covenant with Israel is broken.
- Nowhere in Scripture does it say God has replaced Israel with the Church.
Despite all these things, folks that actually keep the Scriptural Feasts and commandments are said to be misled, "under the Law", not under grace, and putting others under condemnation.
How far we have come! I wonder if much of modern Christianity would be recognizable to the Jewish Messiah Yeshua, who has for so long been exiled in Rome? Or a better question may be, will the fully Westernized, Hellenized religion of Christianity recognize the Jewish revolutionary who restores Israel and judges all the nations from Jerusalem, and finally inviting the whole world to celebrate the Feasts of the Lord with Him? Or will He be written off as too Jewish: "under the Law", too-much-judgement-not-enough-grace?
The thought of judgment, condemnation, and discipline are concepts so foreign to us westerners, it sounds almost like a different religion. Too many are put to sleep by the all-grace, all-forgiving, happy peacenik Jesus preached in the pulpits. Such a Jesus would never judge, never condemn, never correct. In other words, such a Jesus is a pushover. Such is being taught in western pulpits.
