Dear Joy H,
Welcome to the site. You have a very intellingent question.
Many newbie's have asked the same question. Try doing a search under Minors, baptism or contract. I'm sure that you'll get lots of info.
Dutchie also has good information. She's either finishing law school or about to take the bar exam. The best thing that you could do is speak to a Contracts Attorney from or in the state that you where baptized in. Most attorneys don't charge for the first consultation.
I was able to get "incredible" information from a contracts lawyer for free. In my situation, all I want is for the contract to be null and void. I have no interest in suing anyone for money or profit of any kind. Yet, I'll have to wait until I have finished my graduate degree and I'm financially stable to pay all the attorney's fees for justice and peace of mind.
