Funny, I had this exact conversation with a newly awakened one this morning.
our consensus is to use the "new light" in the following manner......
Acting confused ask the question......"so if the slave was appointed in 1919, how are we sure 1914 is accurate if Russell didn't have a hotline to Jesus? If 1919 is based off of 1914 and there was no slave in 1914, how do we know 1919 is right?" (Their eyes and mind should be spinning by now)
"Why did it take the Faithful slave 94 years to figure out who they really are? It seems like if Jesus appointed them in 1919 he would have made it clear then, and not wait almost 100 years. That doesn't make any sense"
"Any rate I look forward to getting the answers to my confusion when we study the article."
