He then asked: “If you do not use the cross, what is the symbol of your religion?”
I replied that the lives of our people must become the only meaningful expression of our faith and, in fact, therefore, the symbol of our worship.
–thus Gordon B. Hinckley, from the Sunday morning session of the April 1975 General Conference. This anecdote was meaningful to him, and he brought it up more than once later.
We of course must be those symbols ourselves. But we must also surround ourselves with saints. Surround ourselves with symbols of Christ. It lifts up the soul.
