I have been trying recently different ways to get fellow Witnesses to use their thinking faculties ,one that seems to work is the following :
"Would you believe in the Trinity if the Governing Body told you to ? "
No!
"Why ? "
Because it is not in the Bible
"Who is the final authority then ,the Bible or the Governing Body?"
The Bible
"If the doctrine of Trinity is your drawing the line ,would you accept that, for others this line could be a different doctrine?"
THAT WAY OF APPROACH SEEMS TO WORK EVERYTIME ,what do you think?
