support Jesus' brothers, regardless of what that means,
I read Jesus' words to mean: help on the personal, humanitarian level, to the most helpless, sick, lowly and destitute; Not at all to support the wealthiest, the power entrenched elite of the self-appointed "anointed".
The parable does not allow for an [that] excuse:
If you gave because you supported an organisation, or did it because just thought of buying salvation, none of that is even mentioned by jesus, so: help the needy, because the creator might just consider that you with empathy thought to help fellow creatures, the lowest.
