I see what the problem is. You fail to understand the keys were symbolic of the powers given to them. They are not physical keys. The gates are real. The Apostles and their names are real. I'm not sure why you would be on a hunt for symbolic keys. If you are still confused then check out Romans 8:11 for further information.
At least the keys were mentioned which is more than we can say for a Pope position, a sinless Mary or Apostolic Succession.
Here we are at
#312 or so, and you seem to have missed the fact we're in agreement that the "keys" were symbolic: there were not actual, physical sets of keys. That's what we were agreeing on in
#230 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.
