Should Christian have faux-Passover?

As we approach Easter I expect that many churches will be doing a Passover memorial meal. I’ve been to plenty, but never personally run one.

But I would have. 

Probably without hesitation.

But, is a Passover meal something Christians should partake in?

Should followers of Jesus imitate a religious feast of another faith?

Further to the point, should they do it and substitute their own beliefs upon another religions sacrament?

How would Christians feel if the shoe was on the other foot?

How would we react if Scientologist had “fake communion”?

How would we respond if Mormons imitated baptisms, stamping their doctrine over the sacrament?

And, why do we stop at Passover?

Why don’t we imitate all of the Jewish festivals? Jesus - being a faithful Jew - also partook in all of them. So, why don’t we do them and cram Jesus in.

Why don’t we commandeer other traditions like Ramadan?

Isn’t the whole practice, the more you think about it, quite insensitive to those whom the practice is still deeply significant?
