It was in the book “Feast of Faith” by Cardinal Ratzinger, translated by Graham Harrison, published by Ignatius Press, ISBN 0898700566, in 1986. The oiginal German edition was published in 1981. On page 144:
“… Surely we must regard it as a priority to reestablish the meaning of the image of the cross. Even now, when the priest faces the people, the cross could be placed on the altar in such a way that both priest and people can see it. At the eucharistic prayer they should not look at one another; together they ought to behold him, the Pierced Savior (Zech 12:10; Rev 1:7). …”
In watching the Vatican’s Midnight Mass with Pope Benedict I noticed there was a large crucifix on the altar, along with the candles. Perhaps this has been influential in the practice at EWTN.
