In extreme briefness and without discussing the currently empirical Christian stance on the matter, pork is prohibited -just like in Islam- in no less than three references in the Bible.
And the pig, though it has a divided hoof, does not chew the cud; it is unclean for you. You must not eat their meat or touch their carcasses; they are unclean for you. [Leviticus 11:7-8]*
All day long I have held out my hands to an obstinate people, who walk in ways not good, pursuing their own imaginations—a people who continually provoke me to my very face, offering sacrifices in gardens and burning incense on altars of brick; who sit among the graves and spend their nights keeping secret vigil; who eat the flesh of pigs, and whose pots hold broth of impure meat; who say, ‘Keep away; don’t come near me, for I am too sacred for you!’ Such people are smoke in my nostrils, a fire that keeps burning all day. [Isaiah 65:2-5]
*The third reference in [Deuteronomy 14:8] is almost identical to [Leviticus 11:7-8]
