You're welcome Matthew. That was just a small sampling from the early fathers. There are citations from Holy Fathers closer to our times as well.
St. Gregory Palamas
One Hundred and Fifty Chapters
- Afterwards, embellishing even as he adorns the world, the one who brought forth all things from nothing allotted in six days the proper and appropriate order to each of those which are his and make up his world. He distinguished each by command alone and brought forth into form as from hidden treasuries the things stored therein, disposing and arranging them in harmony, excellence and aptness, one to the other, each to all and all to each. With the immovable earth as a centre-point he arranged the ever-moving heaven in a circle in the uttermost heights and bound the two together with great wisdom through the middle regions. And so, the same world continues to be both stationary and mobile at the same time. For since the bodies in very rapid and perpetual motion have been arranged all in a circle, the immovable body necessarily had to occupy the middle region as its portion, counterbalancing the motion with its stability, so that the pancosmic sphere would not change position as a cylinder does.
St. Gregory Palamas
Homily Six
To encourage Fasting
Including a brief word on the Origin of the World
He disposed and composed all things in complete natural harmony between themselves, each in relation to all, and all in relation to each. He surrounded the motionless earth, as a central point, with the higher circle of the perpetually moving heavens, holding them in place by means of what lies between, all according to His wisdom, that the universe might stay stable while in motion. When the heavenly bodies all around were moving unceasingly and at great speed, the motionless earth had of necessity to take its place at the centre, its stability counterbalancing the motion, lest the sphere of the universe roll off its course.
St. Kosmas of Aetolia
First Teaching
The Eggs of Easter
WHEN THE FIRST ORDER of angels fell and became demons, the most gracious God commanded and this world came into being. And it is 7,288 years from the time that the world was created. This world is like an egg. And just as the yolk is in the center of the egg, so is the earth made by God to stand without touching any other place. And just as the egg white surrounds the yolk, so does the air the earth. And just as the shell encloses everything, so does the sky the earth, The sun, the moon, and the stars are attached to the sky. The earth is round and wherever the sun goes it becomes day; night is the shadow of the earth.
Here it is night, somewhere else dawn - And just as there are people here on earth, there are some under the earth. This is why the holy Fathers have ruled that we should color our eggs red for Easter: because the egg symbolizes the world, while the red color symbolizes the blood of our Christ which he spilled on the Cross to sanctify the whole world. We too should rejoice and be glad a thousand times, because Christ has spilled his blood and purchased us from the hands of the devil. But we should also weep and mourn because our sins crucified the Son of God, our Christ.
