Thank you all for your comments and suggestions. I have good news. Yesterday, I came home from work and asked him to come with me for a talk. His mother gave little resistance. We went to get some refreshments and had an very enjoyable discussion. He told me that he will get baptized when (and if) he is ready and that no one will pressure him. He understands that to survive in this world you almost have to go to college. He said that that will be his focus. He also acknowledged that there have been many changes in the last few years with the org. (Wow! He is only in his teens and understands that!)
All of this was relief to hear. He is a bright, charismatic boy and I don't want those qualities to go to waste. I don't want him to EVER get baptized. I reminded him that he is my only child and that I love him. I want the best for him and I do not want him to make the mistakes that I did. I can't stop him from getting baptized if that's what he wants to do at some point. But, for now, it seems that he has other priorities.
