Your Bible quotes are out of context with this situation, and you are obviously set in your opinion of the matter. I repeat: A son should take care of his mother, to the best extent that he can. That is my opinion.
Exactly. It is your opinion. My point was that when Jesus took care of his mother, the context was also not only different than this one, but* wildly* different.* Every time his mother was praised simply for being his mother, Jesus always insisted that she was to be praised, instead, for her outstanding obedience to God.* Here is another instance;
While he was speaking, a woman from the crowd called out and said to him, “Blessed is the womb that carried you and the breasts at which you nursed.” He replied, “Rather, blessed are those who hear the word of God and observe it.” Luke 11:27-28
The OP and her brother are not failing in the care of their mother. They have offered her care, and she did not want what they had to offer. They’re not giving her everything she wants when she wants it, and for their mother’s own eternal salvation, that may be just as well.
As for caring for those who cannot take care of themselves, Our Lord commanded us to do this for every least one of his brothers, the same as it were he himself in need. Of course the children of this woman ought to see to their mother’s legitimate needs, to the degree that they can.
My point is that not everything she wants is a need and that they have to accept that until she is truly incapable, it is her choice to reject what she needs in order to get what she wants, and they aren’t bound to get her around the fact that she cannot have both. The truth is, if they don’t save their money for the day when she does actually
need it, and instead give her money to cover penalties for irresponsibility that she could have avoided if she chose to attend to her own needs instead of her wants, they’ll not have anything left for the day when she actually is past the point where she can have her needs met by making better choices.
Where will those families be then? Where will the mother be? She has to be left to her consequences now, both so they’ll not have exhausted whatever resources they could have offered later and so that she might, by facing the consequences of her choices, gain an awakening and start making better choices.
