Molly has mentioned, and I have mentioned, on previous posts that one of the requests we gave my brother at the beginning of this whole process was that our chapel face East, as a simple way of uniting it to Church tradition. Why would one want to have a chapel (or a church) face East? This link has a thorough, yet quick, explanation. It's interesting reading.
I was most interested in the comments of some of the early Church fathers in regard to the value of facing East during prayer. Some of the more salient quotes:
Though Scheme A and Scheme B accomplish the desire for the chapel to face East exactly, Scheme C was a little different. Here's a reminder of how the chapels look in each scheme, with straight left being North, as shown with the little circle to the side in each case:


You kind of feel like reaching into the Scheme C diagram, grabbing the chapel, and twisting it just a little to get it exactly East. And if were going to have the chapel face East, it might as well be exact (any engineer knows there's always some tolerance, but I won't go there). So, we did tell my brother we'd like to have the chapel in Scheme C rotated slightly, and he didn't see any problem with this. In fact, as this point we thought that it may be a nice touch to have a short hallway connect to the chapel so that it could be rotated effectively AND add to the feeling of the uniqueness of the space and drama as you enter it. One commenter on the previous post actually came up with the same idea independently. We'll see what happens, the design modifications continue as we speak (or you read).
I was most interested in the comments of some of the early Church fathers in regard to the value of facing East during prayer. Some of the more salient quotes:
Tertullian informs us that Christian churches are "always" oriented "towards the light."I dispense with any attempt at intellectualism and just say, "way cool." With such a historical legacy of facing East, this was something that we had to try to work into our home. In fact, beyond the historical legacy, with the knowledge of the liturgical basis for prayer toward the rising sun, as Christ is our true light and the light of the world, I think this will really add to our prayer lives in the chapel (I know it will for me).
Origen asserts that the direction of the rising sun obviously indicates that we ought to pray inclining in that direction, an act which symbolizes the soul looking toward the rising of the true light, the Sun of Justice, Jesus Christ.
St. John Damascene says that, while waiting for the coming of the Lord, "we adore him facing East", for that is the tradition passed down to us from the Apostles. Other Church fathers who confirm this usage are Clement of Alexandria, Saint Basil, and Saint Augustine.
