Possible reference to a Mother in Heaven in JC's 1914 hymn.
Joseph E. Cardon, "Only One Mother," Young Women's Journal (May 1922): 304
There's only one mother; she's yours; she's mine,
She's an angel of mercy, sweet and sublime,
She's a savior of men, a heroine divine,
She's your darling mother; she's also mine.
She clings to her own when others have fled,
Who gave them but stones, when she gave them bread;
She cared for them by night and by day,
While others impatient went far away.
