reminds us that the idea of a national day to honor mothers came from radical female Protestant reformers. Here is a taste:
In May 1907, Anna Jarvis, a member of a Methodist congregation in
Grafton, West Virginia, passed out 500 white carnations in church to
commemorate the life of her mother. One year later, the same Methodist
church created a special service to honor mothers. Many progressive
and liberal Christian organizations--like the YMCA and the World Sunday
School Association--picked up the cause and lobbied Congress to make
Mother's Day a national holiday. And, in 1914, Democratic President
Woodrow Wilson made it official and signed Mother's Day into law. Thus
began the modern celebration of Mother's Day in the United States.
