I had always believed that the New Covenant (Jesus) superseded the old covenant (Mosaic law etc.), or at least made important revisions to it. However, you always find people (i.e., Christians) who want to selectively enforce Old Testament law when it suits them. "I'm not going to hell for eating shellfish, but you shall not suffer a witch to live."
My faves are not the dietary laws, but stuff like this:
Quote:
Deuteronomy, Chapter 23
23:1
He that is wounded in the stones, or hath his privy member cut off, shall not enter into the congregation of the LORD.
23:2
A bastard shall not enter into the congregation of the LORD; even to his tenth generation shall he not enter into the congregation of the LORD. |
"You know that vasectomy you were thinking about? Might want to hold off..."

That said, I want to make clear that not ALL xtians selectively interpret for personal or argumentative gain. Just some.
