More ear piercings

I would just wait until you're 18. Right now you'd need a parents signature, so of they won't agree to it you'll have to forge a signature, which is illegal. Once you're 18, you can sign for yourself. As for it being a sin, I'd just pray about it. That's between you and God, not what the "norm" is. In my opinion, we try to make churches look good for God. We plant grass and trees, and place beautiful paintings on the walls. If getting those piercings makes you feel pretty, then go for it. But not without either a parents approval, or being old enough to sing for it yourself.

if you believe it is a sin then why are you doing it? Also if you are under age do not go behind your parents back because that is also a sin if you believe in what the Bible says.

Are you Jewish? I don't see how it would be a sin unless you're Jewish.

I have 2 cartilage pierced in each ear and my holes gauged. Who cares what they think? Your body, your choice. Go for it!
