We know that the coming of the Lord is threefold: the third coming is between the other two and it is not visible in the way they are. At his first coming the Lord was seen on earth and lived among men, who saw him and hated him. At his last coming All flesh shall see the salvation of our God, and They shall look on him whom they have pierced. In the middle, the hidden coming, only the chosen see him, and they see him within themselves; and so their souls are saved.
–Saint Bernard of Clairvaux (1090-1153)
