[Klondike]

I am posting this from memory - please anyone correct me if I am mistaken - as my documentation is buried in my poor file. I believe that Pope Innocent III described the proper way to make the sign of the cross was from right shoulder to left as the Greeks do. I recall that the Spanish had a different custom (left shoulder to right) which became the Latin norm after the 12th Cent.
The early church I believe originally made three small crosses, forehead, lips, and chest as in the Latin Rite. Then there was the great cross, which instead of the chest one touched his feet.
They are all beautiful prayers which is a great way to proclaim the faith.

"Then there was the great cross, which instead of the chest one touched his feet."

We still do this, generally in front of an icon. We make the sign of the cross and then bow low enought to touch the floor with our right hand fingers. This is called a metania and is generally done three times in succession. There is also the practice of full body prostrations which are made after making the sign of the cross. Generally it is done during Great lent when we pray the Prayer of +Ephraim the Syrian. We look like a bunch of Mohammedans and in fact it is from this ancient Christian practice that the Mohammedans got their method of prayer.
