First of all, thanks to everyone who has contributed.
I just finished having my 4th encounter with the same JW, but of course the second person who comes is always different.
Now I try and make sure to get their names, because I know the junior member is green and in training. So I tell the senior member, bring junior with you next time. In this case junior was the senior one’s son.
Anyhow, here is some advice.
Once you mention something that they can not answer they try to change the subject. -Do not let them. Tell them, “Don’t change the subject, please stay on topic!”
They will start walking back very slowly, so follow them to the curb.

I finally asked them, so who is Jesus Christ, and said, “Well, he’s an Angel.” So, I said. “Well then, if Jesus is an Angel and Jesus is the son of God, then what you are trying to tell me is that God is an Angel?” -Stump City! They needed to come back twice on that one.
Anyhow, it’s tough to explain the truth to somebody when they are not enlightened. They are brainwashed and their bible is different than ours. That brings another point, on their first visit when I told them I was Catholic, they tried telling me how the Church denied access to the bible back in the day.
So I gave them the example of how Bibles were pain stakenly written by hand for lack of presses at the time, and how even banks chain up pens, because people walk away with them.
They were able to accept that, but then I asked, “Where can I go buy your Bible?” They then told me, “Well, we can order you one.” So I said, “Hmmm, and your trying to tell me my Church made it hard for someone to obtain.”
But of course, you got to read and know your faith.
And don’t be ashamed if you don’t know everything, better to admit it, then to make something up.
Da gloriam Deo
