Now as to some of the thoughtful issues raised in response to my original post:
1) Our church just cannot afford to pay much more for this family. We have extensive other obligations. But even if we did not have such, if any deadbeat simply could continue to deadbeat, and expect the church to pay, then, at least in theory, anyone could become a deadbeat, and, well... And as apl helpfully pointed out, Paul is explicit in telling Christians that 'he who will not provide for his own has denied the faith and is worse than an infidel'. This is harsh language, very different from the sweetness and light approach to Hallmark Card-style 'Christianity' that is very common nowadays. I seek to have compassion to all, but when I have to decide between having compassion for deadbeat daddio, or his abandoned daughter, well... And remember that, while this man is older and sick now, he actually contracted a marriage after abandoning his support obligations, and then had another child.
2) All this is true for believing Christians within the context of a voluntary church community. But it is not even in the same universe with what is true regarding the state/ society in general. Simply put, children must be supported, period and full stop, and most Americans, and I mean most Americans, high percentage, black and white, Democrat and Republican, etc etc etc, believe that the primary responsibility for supporting children should fall on the shoulders of their able-bodied parents. Almost no one really thinks that deadbeat daddio should be able to laze about, blazing up, whilst the care of his scions should be shunted to the taxpayers, and any attempt to suggest that the state should just assume child support debt obligations is going to be less successful than getting Donald Trump to marry Hillary Clinton. It is true, at least in theory, that some if not many child support owers may find themselves unemployed, and taking away their dls is a problematic solution. A much better one, perhaps, might well be something like this: tell able-bodied daddio that he has 30 days to secure lawful, above-table employment from which support obligaitons might be garnisheed, and if he does not, on day 31, we will be helpfully showing up at 0500 to take him to work on the pothole patrol. Many studs, faced with this dilemma, will doubtless find that the imminent prospect of hard labor will have the salutary effect of focusing the mind towards better, more ethical and socially responsible behavior.
3) It is certainly also true that this sort of cudgel law, taking dl away, is an example of pendulum-swinging. We all know that, for decades, essentially forever, we really did nothing to enforce child support requirements in this country. Then, as feminism increased, more women entered politcs, and more Americans of both genders came to realize that the financial needs of children exceeded those of deadbeats, such laws were enacted. Revisions of such policies are probably a good idea, but wholesale reversion to previous policies, esp in a place such as Massachusetts, well, let's just do a thought experiment here: how exactly might one go about convincing Gov. Maura Healey to do anything like that?
