And I do have an example of how grace and Torah observance to coexist. Biblical sabbath is sundown friday to sundown saturday. It says to not work on this day, for it is the Lord's day. My job, as well as other professions require work on this day (cops, firefighters, emergancy rooms, etc.) through grace I am able to work on this day because again my profession requires it, I can't take every Saturday off, I'm required to work every other Saturday to maintain my job. So through grace I can work on sabbath to maintain my job. I've even spoken to a Messianic Rabbi about it and he agrees with me. Yeshua and Paul when teaching against the Law you have to understand what the Pharisees were doing at the time, and I believe I've said this before. If you take time and study the history and you study of what was gonig in that time period. The Pharisees and Sadducees were adding to the Torah (or in other words adding laws to laws, or adding laws to commandments). When you add to the Torah (which is against Torah), that it legalism. That is what Yeshua and Paul were teaching against, and that's why there was such a problem with it at the time. Now I believe there is no grace in legalitic Torah, but in Torah itself the way it was written and how to follow it and walk in it, I do believe there is still grace in that. But that is a different topic than what we're on.
Back to the topic of the original post.
I'll rephrase the question.
Why is it ok to celebrate a MAN ORDAINED holiday, but the holy days and festivals in the Torah are frowned upon even though they were given by G-D?
Christmas and Easter were ordained by cultures long before Yeshua, his disciples, and Paul every walked the earth, and then they were ordained by Constatine (a man, not G-D) as observation to not offend pagans.
To add to that, does it not say in the scripture that the things we will do and walk in will offend the world? Are we not called be not of the world?
