Passover is a Jewish holiday fulfilled in Christ. He was sarificed once for all time and reenacting that with a ritual of any kind on any day is ignorance of the truth.
How would you reenact a passover? Eat Matza flee to Canada, and have the Lake of the Woods parted? That would be a true reenactment. If you think setting aside a special day to remember how God passed over the Israelites and the passing over of His people from death to life thru Jesus, its you that possesses the ignorance. I don't even mind Christians making this Sunday special remembering the Resurection of Jesus. I just prefer passover.
