Although the Old Testament Law does not deal with cannibalism specifically, as it relates to the nation and kingdom of ancient Israel, it is suprising to many even among academics and biblical scholars, that the subject of Christian Cannibalism does come up in the New Testament. And specifically in the book of Galatians. Which, most surprisingly of all perhaps, does not forbid the practice, but instead gives guidelines for how it is to be engaged in most profitably by the Church of God.
But if ye bite and devour one another, take heed that ye be not consumed one of another.
Christian Cannibalism, just like everything else among God's people, must always be practiced according to the love of God in the renewed mind in manifestation, as Verse 14 exhorts, "Thou shalt love thy neighbour as thyself." Verse 15 of Galatians 5 shows exactly how to walk in that kind of love when practicing Christian Cannibalism.
First note that Verse 15 says "if you bite and devour," So first of all we note that Christian Cannibalism isn't a matter of law, as in "thou shalt," but in the essence of "if" you should do so. So Christian Cannibalism is never out of law but always out of love.
Then note who Verse 15 says is talking about. It says, "if you bite and devour one another," that is, one another as brothers and sisters in Christ. So it's not talking about the unbelievers from outside the pail, so to speak, who we are going to bite and devour.
Which means that Christian Cannibalism, to be operated properly according to God's Word, must be practiced only within the flock. Bringing, of course, new meaning to Galatians 6:10's admonition to "be especially good to the household of saints." Yes, and on a silver platter delectable too.
Then Verse 14 says "take heed." Take heed of what? That we "be not consumed one of another." So if I'm going to take bites out of your leg, I won't eat the whole thing, but stop at the knee so a prosthetic foot will be easier for you to fit. Or if I consume one of your arms, I will leave the other one alone so you will still be able lead songs during Twig meetings.
That is what I call the Mystery in motion. (Of course, you will have to figure out a way to prop up the songbook, but you can at least believe God to do that. Right?)
Thus when it comes to Christian Cannibalism, the Word of God itself, rightly divided, shows exactly what it means to live according to the command of Verse 13 to "by love serve one another" and make life yummy!
