IIRC, Jesus died so that we may be saved even when we break some of the gazillion Old Testament rules.
And those Old Testament rules that had as their primary purpose to represent some spiritual principle symbolically, which is either accomplished by the death of Christ or seen much more directly afterwards, are all passed over in the New Testament: the sabbath, clean and unclean foods, sacrifices, not mixing fabrics, various holidays, and a host of others. Hence, it is not only acceptable but downright appropriate to eat ham at Easter.
Your entrance into the thread, Larry, reminds about the worst thing about Passover: no beer, and no whiskey.
I'm drinking blackberry Manischewitz as we speak - it's Passover approved! Nothing to do with religion, I just like it.
