"The Church as a Church requests its members not to play cards. I hope you understand me, and I want you to know that I am speaking for the Church when I ask the people to let cards alone."
Heber J. Grant Gospel Standards pg 42

I do not have access to this book - if you have it will you check the reference for me?

JOEL - I have the book. Here's the entire quote:

"By the way, I hear that card playing is becoming very, very popular, and that the Church must be in favor of card playing because the Church authorities never say anything against it. From the time I was a child and read the Juvenile Instructor, published for the benefit of the people, I have read nothing except condemnation of card-playing and the wasting of your time in doing something that brings no good, bodily, intellectually, or in any way, and sometimes leads your children to become gamblers, because they become expert card-players. The Church as a Church requests its members not to play cards. I hope you understand me, and I want you to know that I am speaking for the Church when I ask the people to let cards alone."
