Jon Ray, you forgot the one about not having sex with animals. That is also 100% exclusive to Mosaic Law. How many of the tattoo proponents think that it is acceptable behavior for a NT Believer to have sex with animals?

Also, the tattoo issue can be a little tricky. Reading the passage in context, seems to be dealing with actions that were made in worship of the dead, a pagan practice that was forbidden. Cutting yourself or making marks on your body for the dead is what appears to really be the restriction.

HOWEVER, since it is not all that clear, the real attitude of the Believer should ask, “Why do I want a tattoo anyway?” I can only speak for me, but I just don’t get the desire for them. I have absolutely no desire to get a tattoo, it just doesn’t make sense. The Bible says not to do it. Whether it’s only about worship of the dead, or whether it’s an outdated OT Law, or whatever, it’s not clear enough to justify doing it, and I don’t get the premise. Why would you want to do it in the face of the commandment not to, unless in your heart you would rather place your own desires above an issue that has a direct commandment against with a vague at best argument to void that commandment?

A final thought on this:

For this mitzvah that I am commanding you today is not too difficult for you, nor is it far off. It is not in the heavens, that you should say, ‘Who will go up for us to the heavens and get it for us, and have us hear it so we may do it?’ Nor is it across the sea, that you should say, ‘Who will cross over for us to the other side of the sea and get it for us, and have us hear it so we may do it?’ No, the word is very near to you—in your mouth and in your heart, to do it.
Deuteronomy 30:11-14 (TLV)

Mitzvah, for those who may not know, is the Hebrew term for the Torah Laws of God.

It’s harder to work at justifications and loopholes to disregard God’s Law than it is to simply obey it. That means that the true burden of the Law is on those who look for reasons not to obey. Those who obey are the truly free ones, free from the stress of trying to justify rebellion, free from the curse that comes with disobedience (Deuteronomy 28), free from sin (the transgression of the Law). If you want to be free, just do what God said to do and don’t do what He said not to do. That is true freedom.
