It is real moments like this that can lead us into having a "real" discussion as adults within a family.To be honest, I think they are a bit ashamed of how they lost their composure. But I guess they feel about me about the same way I might feel towards a child who told me tarot card readings and witchcraft were helping them draw close to God. At the end of the day, nothing I can say will ever convince them. But if I can show them you can still be good and well adjusted in ways they also accept as being good without being totally active in the church, then at least I can alleviate some of the torture their minds are feeling right now.
I have (3) adult children & none are active in the church. All of them are well adjusted with lives of their own.
They are married with children & careers. I couldn't be happier or prouder. (is that a word?)
We have had ups & downs. They can talk with me about anything. I can do the same with them. We don't always agree.
We do respect each other & don't try to take the world seriously. I wish I would of had the same relationship with my parents.
It is moments like what you're going through where the parents realize (hopefully):
1. the child is an adult now.
2. the adult (child) is making their own decisions & living with the consequences.
3. we can still be friends & respect each other's views & opinions.
I wish you the best.
