I personally do not see the point in tattoo's or piercings. Most people do not and cannot bring glory to God by such outward adornements. However, I do not believe the LORD will judge anyone for having either of them.
It is interesting to note that in the OT an Isrealite would pierce the ear of a slave who did not wish to leave his master using an awl. Because of this, a pierced ear was often symbolic of slavery or ownership. Once this was done, the slave was the servant of his master for the rest of his life.
I must confess that I have felt tempted to get a tattoo once or twice. Perhaps a sweet OT verse in Hebrew on my arm or back. Then I remember that the word of the LORD is written on my heart and I do not need any external reminders or proclaimations of my love for the LORD.
I will contribute a few verses to the subject for everyone to read and think about.
1 Timothy 2:9-10
9I also want women to dress modestly, with decency and propriety, not with braided hair or gold or pearls or expensive clothes, 10but with good deeds, appropriate for women who profess to worship God.
This would appear to be a much more strict request then the LDS prophets. Why? The Bible holds nothing back and the writers are not trying to please men or women. In the case of the LDS church, it would appear that they have lost (or never had) truth on what the Bible considers modesty. It's not only them but probabley atleast 90% of the world with them.
1 Peter 3:1-6
1Wives, in the same way be submissive to your husbands so that, if any of them do not believe the word, they may be won over without words by the behavior of their wives, 2when they see the purity and reverence of your lives. 3Your beauty should not come from outward adornment, such as braided hair and the wearing of gold jewelry and fine clothes. 4Instead, it should be that of your inner self, the unfading beauty of a gentle and quiet spirit, which is of great worth in God's sight. 5For this is the way the holy women of the past who put their hope in God used to make themselves beautiful. They were submissive to their own husbands, 6like Sarah, who obeyed Abraham and called him her master. You are her daughters if you do what is right and do not give way to fear.
One could argue that the above verses from 1 Peter 3 could refer to a woman solely relying on outward adornements to be beautiful while neglecting spiritual beauty. However, if we keep what Paul wrote in mind then gold, pearls, braided hair, and expensive clothes are not modest.
Isaiah 3:16-23
16 The LORD says,
"The women of Zion are haughty,
walking along with outstretched necks,
flirting with their eyes,
tripping along with mincing steps,
with ornaments jingling on their ankles. 17 Therefore the Lord will bring sores on the heads of the women of Zion;
the LORD will make their scalps bald."
18 In that day the Lord will snatch away their finery: the bangles and headbands and crescent necklaces, 19 the earrings and bracelets and veils, 20 the headdresses and ankle chains and sashes, the perfume bottles and charms, 21 the signet rings and nose rings, 22 the fine robes and the capes and cloaks, the purses 23 and mirrors, and the linen garments and tiaras and shawls.
If jewlery leads to a woman (or man) being haughty then it would appear that the LORD does not approve of such things. However, as Pheobe pointed out and Christ taught :
Mark 7:20-23
20He went on: "What comes out of a man is what makes him 'unclean.' 21For from within, out of men's hearts, come evil thoughts, sexual immorality, theft, murder, adultery, 22greed, malice, deceit, lewdness, envy, slander, arrogance and folly. 23All these evils come from inside and make a man 'unclean.' "
Perhaps ones intention or purpose for wearing jewlery, piercing their ears, or getting tattoo's is everything. However, it is not for me to judge. Review the scriptures above and allow the Spirit to guide you.
Christ guide us,
