I’m a member of Esperanto-USA, and it recently adopted a new gift acceptance policy that I thought churches might use as input for developing their own. Esperanto-USA customarily publishes its governance and financial information in English, so there’s no need to learn la internacian lingvon to read it. Note how it clearly assigns responsibilities, makes clear expectations of donors for large gifts and avoids poison-pill gifts.
And while we’re at it, give your local food bank or pantry cash, not the refuse from your pantry. It’s looking like a hard fall in the United States, and cash is far more useful.
