I don’t think this is an issue of “Timmy didn’t get a Mercedes on his 16th birthday, so this family is terrible!” I think the OP is referring to a household where children are not being cared for properly. They should not have more children when they can’t care for them. It’s not fair to create suffering.
That could be your opinion. That could be the opinion of someone in that marriage. But it cannot be Catholic teaching. We do not dictate when a married couple must stop engaging in the marital act. And it is not consistent with Catholic theology in present third world countries or historical situations.
Theology is false if it is not consistent.
Using your idea of it not being fair to create suffering you would think that the Church would have had ample opportunities to agree with you. It has not. Where Christians are persecuted today not only does the Church not tell them not to have children because of potential “suffering” it actually marries them making them promise to bring forth children. Historically when the Church suffered much persecutions. It grew. Not only by converts but by procreation. In extreme disease and poverty where many of a couples children would die, Catholics were still under the command. In Africa, Latin America etc it continues to grow. Not because these poor people are not taught NFP but rather because that is what we are to do as married Catholic children of God.
The earthly answer is to stick our selves between the sheets of this couples bed and tell our own opinions of how many children they should have. The Catholic and Holy answer is to help them support the ones they do have and to help them access the tools to be able to make it on thier own. If that is financial, physcological or educational so be it.
Such a misunderstanding of how to help people is on display here.
Call CPS.
Offer to help with the Kids.
Get a group of people together after Mass to buy food and clean their house.
Educate.
Pray for.
Empathize.
These are what we are called to do.
Judge.
Condemn.
point fingers.
insert ourselves between the marital embrace.
These are what we cannot do.
Your view of suffering is off base.
What the couple could be doing wrong is not treating their children properly. The mistake is not in having the children of future children, the mistake is in the care of the children or future children. That is what needs to be remedied.
Remember we live in a world where those of us who can and do provide for our children are STILL looked at like we should not have more. From doctors who push ABC, to the innocent comments at the grocery store about if we are done yet. It is important that we do not let that worldly and material thought invade and perverse our theology. Just as we are so quick to defend the idea that “how dare we tell a couple they do not have just reasons to abstain” we need to be consistent with that idea that we do not belong between a naked husband and wife. Even when the choice is to have a child.
It is not our business and we are questioning God’s vocation for a couple which we have no knowledge of.
The only person I know of that it would have been better if he were not born, was Judas.
