Well you're mistaken on a major issue. Notably on your statement that all of the coveant of Sinai was given through Moses. The ten commandments were spokenn directly by God to the people....completely unmediated by Moses (Exodus 19:1, Duet 10:4)
I wouldn't call it a mistake. You simply read too much into my comments. Moses is clearly identified in Scripture as the lawgiver of Sinai. It was through Moses that the word of the Lord was brought to the people. While God spoke the ten commandments, He gave them to the people by the hand of Moses (Ex. 34:28,29).
However, that doesn't help you at all in your position, since we are not speaking of the "ten words" but rather we are speaking of all the ceremonial laws given by Moses to the people, esp. the bloody feast days of the older covenant like passover. Passover was part of the Sinai covenant brought to the people by the hand of Moses. So it would be helpful for you to stay on topic. Otherwise I might get the impression that you are dodging the issue that passover celebrations have ended.
"Since I'm not a dispensationalist I do not find anything in the old testament about "Christ's return" and a turning to bloody, old covernant feasts. "
You don't believe Christ is going to return to earth?
Actually I do. I just don't swallow the dispensationalist party line on how it will happen.
The old testament prophecies were highly symbolic and, frankly, they were all meant to point to Christ's coming to redeem His people. This all happened 2000 years ago. The ongoing work of Christ is to establish His church throughout the world, and to disciple the nations.
It is no coincidence that Jesus spent much of his time preaching on the mount of Olives.
"And beginning at Moses and all the Prophets, He expounded to them in all the Scriptures the things concerning Himself." (Luke 24:27)
If you believe that that biblical prophecies are more symbolic than literal and none of them have relevence for the world today then there's not much to talk about. There's no common frame of reference. Thank you for the discussion.
