Hello Baxley,
I think that much would depend on what one means by "celebration", how far it's taken, and what's done. As an example, Christians have every reason to celebrate and give thanks for JESUS CHRIST every day. I don't celebrate JESUS CHRIST as a matter of Law and ritual, rather as a matter of Love and appreciation. HIS Birth, HIS Crucifixion, and HIS Resurrection as our Living LORD and Saviour is the central focus for my entire life. I do give thanks for this most perfect Sacrifice and GIFT every day.
HIS Blood on the CROSS is forgiveness of my sins and is a "Passover" for the punishment that I deserve. Many events of the Holy Bible were shadows of things to come, and JESUS CHRIST was the REALITY that replaced those shadows. The first Passover was a shadow of things to come, and the CROSS is the REALITY.
In one way, it sounds odd that someone would celebrate the horrible and cruel Crucifixion of JESUS CHRIST on the Cross, but this is the most precious and important event of human history. I don't celebrate the cruelty and pain that JESUS suffered, but I do celebrate how JESUS and the Cross have impacted every corner of my life and changed me forever. I celebrate the fact that I belong to JESUS CHRIST for eternity, and I celebrate the fact that I've been rescued from the curse of sin and death.
I wouldn't understand why a Christian would celebrate or give thanks for Passover, most especially in a legalistic or ritualistic way. BUT, I would understand a Christian giving thanks continually for JESUS and the CROSS. It wouldn't be in a legalistic or ritualistic way - just love, praise, worship, thanks, and appreciation to our LORD and SAVIOUR.
Thanks be unto GOD for HIS unspeakable GIFT!, JESUS CHRIST, our Lord and Saviour forever!
Love In Christ,
Tom
John 17:21-23 NASB that they may all be one; even as You, Father, are in Me and I in You, that they also may be in Us, so that the world may believe that You sent Me. "The glory which You have given Me I have given to them, that they may be one, just as We are one; I in them and You in Me, that they may be perfected in unity, so that the world may know that You sent Me, and loved them, even as You have loved Me.
