Andrew of Caesarea
Here He who was slain as a Lamb will come in the glory of the Father as Judge, upon the clouds.
This may mean upon the bodiless noetic powers, or upon something like the cloud that overshadowed Him with the holy Apostles on Tabor.
Every eye will see Him coming with glory. Those who crucified Him, and the tribes of the earth that remain in unbelief, will mourn (Mt 24:29-30).
"Yea, amen" means: truly, so it is. For by these words one and the same meaning is signified in both Greek and Hebrew. Amen means: let it be.
