Thanks for the interesting replies.
I often hear the argument that we're no longer under the law and we have liberty in Christ. However, we do not have liberty to sin. And we know that sin is transgression of the law (specifically, the moral law), and there's also sins of ommission. So, how do we deal with these so-called "gray" issues?
A lot of people quote the verses in 1 Cor., Colossians, and Romans about meats. Even Jesus said that it wasn't what went into a man that defiled the man but what came out. So, eating meat and sticking metal in your face are two different areas (the principles can be used, but I think there's a better way of addressing the issue than to use these verses, in my opinion).
1 Cor. 10:31: "Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God."
When I look at this verse, it makes me wonder what the motivation for people getting piercings are. Are they doing it for the glory of God? When people see the person who has piercings, will they say, "God sure is a mighty God and is holy and just, etc...this person sure exalts his/her God with their appearance!" Honestly, I've never done that. My first thought when I see someone w/ piercings is, I need to witness to that person.
My next thought would be, is this practice of piercing of the world or is it of spiritual? I think most would agree that this fad is of the world given the types of people who do this. And yes, this is a stereotype. I can say from experience, with the people I've talked to who have done this, that the majority do this because of some sort of rebellion. They carry the attitude of "I don't care what you think!", "I'm different!", "You can't control me!". The funny thing is, is in their quest to be so different, they're involved in a generation where everyone's doing it! So much for being unique. But, the issue here is Christians. Should Christians conform to a fad of the world that involves mutilating the temple of God? I believe 1 John 2:15-17 addresses this: "Love not the world, neither the things [that are] in the world. If any man love the world, the love of the Father is not in him.
For all that [is] in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world.
And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever."
also, Romans 12:1,2: "I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, [which is] your reasonable service.
And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what [is] that good, and acceptable, and perfect, will of God."
So, when we examine the motives for piercings, is it really to glorify God in their bodies or is it to bring attention to themselves for their own desires?
