first… the keys where given to Peter and by tradition we know they where passed to the succesors.
but… if you read the prophetic book known as the apocalypse or revelation you will see that at some point Yeshua has the keys. In my little mind this is proof positive that there will come a time when there is no succesor on earth with the keys unless it is the second coming.
Now that is fine and well. The problem arises when cults teach that nobody living on earth has the keys and then turn around and attempt to celebrate communion.
It is my belief that when the time comes that Yeshua reclaims the keys; communion is no longer available or at the very least extremely difficult to determine.
It is my thought that true communion is the only way one can possibly know Christ. What I say is if the Christ you know is by any other means you have a personal relationship with a devil.
If at the moment of recieving Communion you know Christ you are so blessed and can know with certanty that it is the true and living God that you know. But if you believe yourself to know Christ by any other means you are in a very bad spot.
