That was 80+ volleys ago. It does get...long.
OK, so we've long been in agreement that these were not physical keys. What I was disputing was this assertion of yours:
"Rev. 21:12 tells us that Heaven has twelve gates. Whoa!! You don't suppose all twelve Apostles were given keys, do you? Rev. 21:14 says yes..."
...when in fact there is nothing in the Book of Revelation at all about the Twelve Apostles having keys.
Peace.
It was inferred. After all they were symbolic keys and the point was they were all given these powers. Instead of looking for keys you should have been looking for evidence they were given these powers. The gates with their names on them should have sufficed in that regard.
Peace be with you
