This meme (which has been making the rounds over the last few days) is purely a case of thoughtless and blatantly dishonest church-bashing…

Even if the claims it makes were accurate (which I highly doubt: given the unsettled conditions in Houston, how would you find and verify such information?), most churches do not have the resources to do much by themselves, especially on short term notice – they tend to rely on their denominations to do the heavy lifting in such cases. Their parent organizations have the trained staff and dedicated resources (and fundraising capabilities) needed to support such work. Local churches don’t.
There are definitely a number of denominations, including my own – the UCC – that are ramping up major support efforts, with the intent (and proven track record) of being there and staying there to help folks rebuild, years after the news cameras and social networking site feeds have forgotten about them and their needs.
For more information on what the UCC is doing, read this article on their website:
