My personal view (now) is that God's name is NOT 'Jehovah', but a name lost in ancient Hebrew. If 'Jehovah' ever appeared in the NT, then what is the Greek translation?
The JWs insist that 'Christendom' removed the name to mislead the people, yet it was a Catholic monk who 'invented' Jehovah and presumably the Catholics inserted it into the OT. If the JWs were so pedantic about getting God's name right, they would surely adopt something closer to the original pronounciation than a Catholic monk's invention.
I (now) believe that JWs break the Commandment, ''I am the LORD your God who brought you out of the land of Egypt, from the house of slavery. You shall have no other gods before Me..." ...because they have invented one in HIS place.
