I remember an article in the Watchtower of August 1, 1995, page 20, entitled “Our Rich Spiritual Heritage.” And I’m fairly sure that there was also a talk by that title at an older district convention or circuit assembly about ‘appreciating our rich spiritual heritage.’
So the Watch Tower organization wants us to ‘appreciate our “rich” spiritual heritage,’ but they don’t want us to be able to know exactly what that heritage actually is.
