Then answered Peter, and said unto Jesus, Lord, it is good for us to be here: if you will, let us make here three tabernacles; one for you, and one for Moses, and one for Elijah.

Cyril of Alexandria
AD 444
Peter didn’t know what he was saying, for before the Savior’s Passion, resurrection and victory over death and corruption, it was impossible for Peter to be with Christ and to be permitted into the tents which are in heaven. These things would happen only after the Savior’s resurrection and ascent into heaven.
