Re: " ...I believe the Passover is the start and finish of the Christian Church. I believe it is the only Feast that Christians are to keep "
 
I found the article and particularly your above comment interesting particularly because the Lord has led me to keep the Passover some years ago, and when during one of those years I began to doubt whether it was necessary for a Christian to keep the Passover, the Lord reminded both me and my wife - so that year we started keeping the Passover a few days late. Aside from the Sabbath and Passover, I have not been led (or have not yet discerned being led) to keep any other specific days.
