Of course, but, by being very clear about what the law is and what the ramifications of breaking that law are, as an adult they can make an INFORMED decision to break that law. The second half is to let your kids know, if you break either civil or Church law, I will not be a party to it. I won’t drive the car if you rob a bank, I won’t help you sell drugs, and I won’t attend an invalid wedding. If you break civil law and go to prision, I will visit you and love you the entire time. If you break Church law and endanger your mortal soul, I will still love you and pray for you, I will listen to you and visit you - I just will not support you in that error.
We have to show our kids - through our actions - that we will stand up for what is right. My son knows that I have dear friends who ARE gay. He knows these people, and knows that I love these people. I do not shun people - heck, I’m a real softie.
I have a friend who is having an affair. I still love her and go to her home and she comes to mine - we are good friends. I REFUSE to let her use me “cover excuse” so she can meet her lover.
Love the sinner, hate the sin.
