I think the distrust is a real issue, on many levels. There is also very little understanding that family is about relationships not biology. It is a very unloving parent who disowns a child because they are different or choose to live a different way of life. Our children (and grandchildren) know our values; the fact that one is divorced and lives with his partner does not mean that we disown him and his partner (nor their children, our grandchildren) - we respect them and their choices and pray for them and love them, and they respect us and our choices. Hopefully the hurt of marital failure will be healed, and he will not allow one failure to blight the rest of his life. I am equally sure that God loves and accepts him/them as they are more than we do. He/they know that we love and trust them, which is what God asks of us.
