There are many who will "Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage.". And again, "Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace." So, if abstaining from pork (or any of Torah) is not a matter of justification, then it may be eaten under grace by those who have such knowledge and it may be laid aside, in love, for the benefit of others.
