She believed that the Christ Child called her to do His work and that all people regardless of their condition in life can serve the Lord.
"Miss Mary Merrick's long life was an inspiring expression of the power and beauty of Christian charity. She saw the image of the Infant Savior in every poor child and it was the Christ Child who conferred upon her a long life of amazingly successful activity that defied an almost lifelong infirmity.
It was ineveitable that she establish the Christ Child Society. Both in spirit and accomplishment, no society has better deserved the sublime name. Miss Merrick from her bed of pain, perpetually dynamic and devoted, has a lesson for everyone who professes to be a follower of Christ."
