Listening to the Australia Bethel dedication talks 1983 {avalible on cassette} Loyd Barry of the Governing Body tells of how an old Missionary Brother aproached him and said: "The society can change any doctrine they want...but please Brother, don't change the doctrine regarding 1914." {He had hoped to live thru to paradise} Loyd responds: "Brothers, we have NO intension of changing the 1914 doctrine."
Remember this was just after Raymond Franz handed out to the Governing Body members, copies of an article written by an Elder dis-proving 607 and 1914....I think in 1979.
So, after Loyd Barry died, in 1993, the 1914 generation theory was thrown out...that missionary had long since died.
