Are you sure it was from Christian Science and not the Christian Science Monitor which has been a long-time sponsor (and if I recall occasional reporting partner) of NPR.
Not mad, disappointed. It just seems embarrassing for them that they're struggling so hard to live up to their value of being "listener supported" that they have to accept sponsors like this to survive.
It sounds to me like you are disappointed that the liberal bubble isn’t as thick as it could be. That even accepting supporting money from the bad people is compromising.
It seems that you are implying that the sponsors of NPR get a say in their programming and reporting? Seems like that is the thing I would be upset about, not that the “wrong people” are supplying the money.
It’s NPR, and clearly an atheistic listener there. Are you surprised at this complaint? Christianity is largely anti-science and works against many of the purposes NPR espouses like climate, public health, science and tech, major topics all over NPR. It’s not a stretch to accept this complaint as valid to many left wing rationalist NPR listeners.
The Christian Science Monitor has long had top quality journalism, and sections on religion. What is their relationship with Christian Science (and what is that? is there a unified institution?)?
Christian Science is a church founded by Mary Baker Eddy in 1879. They're most famous for believing in faith healing, which is part of a larger collection of beliefs with a "mind/faith over matter" flavor. They have churches throughout New England. In practice, they tend to be pretty mellow in that old-school "New England religious movement" sort of way.
The Christian Science Monitor is a well-respected newspaper associated with the church. The few times I've read a paper copy, there was usually one editorial with a religious theme. Their religion did not otherwise color their reporting.
I am not the least bit suprised that the Christian Science church might support NPR. Demographically, Christian Science members probably have very high overlap with NPR listeners. And they are, after all, a church which is best known for being associated with a newspaper. I would not be the least bit surprised if they donate to NPR mostly because they want to support public radio.
Christian Science Monitor has been my favorite news source for a long time despite not really being religious. It's so objective and fair even on the most contentious of topics, and really tries to understand the human experience.
They were founded by the same woman, Mary Baker Eddy, like a century ago, but today they just have one specifically-cited Christian Science article in each print.
It seems they may have the same owner still, but seems like they very much have editorial independence, judging by the things I read.
There is, main HQ over in Boston. Both orgs were founded by the same people.
I believe the Monitor offices are right next to the main Christian Science complex/are in it.
