I didn’t know that about the Red Cross. Many churches sponsor their blood draws.
The Red Cross is purely a secular organization and one very much eaten up with political correctness:

Mind you, they do some good things. Just keep in mind that if you want to give to a religious organiation doing similar work, you’re looking at the Salvation Army or Samaritan’s Purse.
