Tattoos

 

Leviticus 19:28 ESV
(28)  You shall not make any cuts on your body for the dead or tattoo yourselves: I am the LORD.

The human body was designed by God, who intended it to be whole and beautiful. Disfiguring the body dishonored God, in whose image the person was created. Cutting one's flesh for the dead and tattooing (or perhaps painting) one's body had religious significance among Israel's pagan neighbors. In Israel, such practices were signs of rebellion against God. Nelson’s New Illustrated Bible Commentary

Genesis 1:27 ESV
(27)  So God created man in his own image, in the image of God he created him; male and female he created them.

The bible is quite clear on this matter.  Mankind is created in God’s image – to mar our bodies in any way is to say that God didn’t get it right the first time or that we know better than God how we should look.  Such is rebellion.
