If I understand you correctly, you question the idea of policy of the Church as part of your more basic argument that the Bishops should not have issued this statement as they did. Is that a fair statement of your position?
Yes.
If so, then on what grounds do you say this?
There is no bright line separating those issues where the bishops’ involvement is appropriate from those where it is not. I clearly set the bar higher than most bishops do. My concern with their (persistent) involvement in political issues is that it tends to poison the conversation by separating the sides into the sheep and the goats, the moral versus the immoral. That perception runs through all of these discussions on any issue on which they speak.
That said, there are times when the issue is so clear that it would be a dereliction not to speak out. So, how are we to distinguish where their involvement is appropriate from when it is not? I haven’t thought about this enough to come up with a general rule, so I’ll address just this particular issue.
If a bishop is going to interject himself into a political controversy he needs to give every indication of both impartiality and comprehension, otherwise it is not unreasonable to view his involvement as being to some degree politically motivated. On this issue the bishops fall short (in my opinion) on both counts.
First, this action is not new; it has been the law for 20 years, and the bishops are just now coming forward to condemn it? The timing may have been motivated by what (appears to be) the increased scale of the separations, but if the action is so immoral they should certainly have come forward before to challenge it. That they bring this up only now under this administration justifiably raises questions regarding partiality.
Second, and I’ve mentioned this before, if they understand the full scope of the problem they give no evidence of it. The (current) options are to hold the adults and separate the children, or simply release into the country anyone who comes across the border in the company of a child. Their approach turns children into free-access tokens and encourages the separation of the families by the smugglers before they ever reach this country. That the bishops never discuss any of the problems with their solution or even acknowledge that other concerns exist in my mind invalidates their involvement.
