One only needs to study the Greek words to understand that the translation "will be bound" is in error. The Greek word is eimi which means I am, exist. Here is the word used again.
John 8:58 Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.
Jesus exists eternally as do the things the apostles were to bind. Nothing in that passage says that the what the apostles did would begin to be bound in heaven. They could only declare what already existed.
Still waiting on you to tell us what your degree is in. If you can’t do this than supply the source of your information.
That is becoming quite comical
και δωσω σοι τας κλεις της βασιλειας των ουρανων και ο εαν δησης επι της γης εσται δεδεμενον εν τοις ουρανοις και ο εαν λυσης επι της γης εσται λελυμενον εν τοις ουρανοις (Matthew 16:19)
αμην λεγω υμιν οσα εαν δησητε επι της γης εσται δεδεμενα εν τω ουρανω και οσα εαν λυσητε επι της γης εσται λελυμενα εν τω ουρανω (Matthew 18:18)
