I know that you are suffering and weakened but it is very important that you not allow your son to continue to harm the whole family. Your son’s rebellion against you, his mother, and God must face consequences; you must take strong action against your son even if you have to have conflict you’re your wife.
I am sorry to put this responsibility on you but if you do not stand up you will become a door mat and things will get worse…Although not exactly like your situation, there is a story in the bible about Eli the priest that did not give his sons consequences and the sons forced God to put an end to their rebellion in a very serious way (death). In addition, the son’s rebellion caused the whole family to suffer a lot, including the father. If you want to read the text for yourself it is in First Samuel, chapter 2 and 3.
I know that your situation is somewhat different than Eli but the point is that the father has the obligation to take action when the son is rebellious.. The text in Samuel clearly shows that God can take very serious actions against those that defy God and disrepect God and their parents.
Jose presents another problem that needs to be dealt with.
Jose, I would suggest that he does not actually have accountability as the father because, although he was willing, the mother would not allow him to assume his rightful role to her minor child in his home.
Unfortunately I have some experience with a family connected to me where the natural mother countermanded and put down the natural father to their son, and the toxic results and dysfunction were very similar to the above (minus the drugs and stealing). When the father took steps to try to overcome this, the wife alienated the two daughters as well so most evenings when he arrived home from work there was a hateful outpouring against him by the entire family. There was simply nothing the father could do short of leave the family and divorce the wife, which two Christian counselors advised him to do for the sake of his sanity. Today the oldest two children still bitterly hate him and the youngest is finally starting to open up intermittently, but the oldest two influence her to keep going back to cruel treatment of her father. It is a well of grief to this father who still deeply loves his children.
In this case the minor child, though he was willing to father it, was withheld from his fatherly attempts.
I agree with everything you suggested he do from an ethical/moral standpoint and for the good of the young man, but it will cost him his marriage to a wife he still loves and potentially cause the daughter's home situation to explode.
Girls are very emotionally traumatized with this type of drama in their homes. The OP hasn't said how old she is, but my guess is adolescence - early/mid teens. This is a time in her life where she needs protection and stability or else she could suffer emotional damage that will take some years to overcome, if she does.
If the OP takes the action you suggest (which would be moral and ethical), based on what we know about his wife, it's likely she would become embittered, embattled and the daughter would suffer alienation against him in his absence. Now he has lost two children instead of one, and to the second child's lasting harm.
So, is his concern the son or is it the marriage along with the daughter?
I would suggest his concern is the marriage and daughter, and that he leave the fool to its mother because that's the only path she has allowed him with her (not his) son.
Thoughts?
