Your understanding of the Trinity doctrine appears to be very similar to my father's understanding of it.
It is an understanding that he aquired from the Watchtower Bible and Tract Society.
It is an understanding that is very fragile as it has little scriptural support. That is why it is so easy for him to argue against it.
Neither my father or my mother understand the doctrine of the Trinity, despite having being opposers of it for seventy years.
I didn't understand it for fifty two years.
Do you really understand it??????
....or are you making the same mistake as my family???????
