I know that they have heartfelt, good intentions. Credit should go to them for doing what most of us would do if we thought it was the right thing to do.
But Christians who think they have to observe and take part in the Jewish festivals, either aren’t impacted by or they dismiss the fact that some of the Jewish feasts require sacrifices at the Jerusalem temple. That the temple doesn’t exist anymore, excites no alarms that perhaps the festivals are obsolete.
They must not know that Jesus is the substantive fulfillment of those festivals. They must not know that the festivals were mere shadows and types pointing to the Messiah, and that they, with other Mosaic hand-written ordinances, were nailed to the cross when Jesus died (Colossians 2: 14, 16, 17).
The following reinforces that point. I Corinthian 5: 7, 8 says, “Clean out the old leaven so that you may be a new lump, just as you are in fact unleavened. For Christ our Passover also has been sacrificed. Therefore, let us celebrate the feast, not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.”
Clearly this says that Jesus is the Passover. He is the Passover for all who believe in Him. The past sacrifices of slaying a lamb, and other attendant measures, have been done away with.
Sincerity and truth in Him are now the ingredients and offerings with which the Passover – Jesus – is celebrated. And this, of course, is done at any time. This is a biblical principle that is applied to all the other festivals and feasts as well.
I heard someone put it this way concerning Jesus being the fulfillment of types and shadows. “Why stare at a photo of a loved one when that person, in flesh and blood, standing before you, can be embraced?”
Jesus not only stands before His believers, but is in them as well.
