On a positive note, in my search for a Seder to attend I found these folks:
Cornerstone Baptist Church - Winning Souls And Making Disciples
This is a mainstream, Baptist church teaching Torah and holding a Seder.
I likely will not attend their Seder, as doing so would mean not having one at home, and one's first ministry is always to their own home. However, I see they hold a Sabbath gathering at 11 am each Sabbath. One day soon I think I will stop in on a Sabbath morn, and see what they are teaching.
The time of the grafting of the branches is coming, and the outpouring is beginning. Ten years ago, when I began to observe the feasts, I was the only one I could find within 500 miles of my home. Period. During that time, things have changed rapidly. Not only are Christian churches beginning to see the prophetic truth of the Feast days and the Acceptable Calendar of Yahweh, Jews are beginning to see that Messiah was and is and will be again. The he died and was their Passover lamb. Literally, his blood is upon them. The answer lies somewhere in between discarding the law and ignoring salvation, and we grow closer to finding it everyday.
