The Cross is atrocious. The work was done by sculptor Keith Monroe and was part of the chapel from the beginning. As is plainly seen, it was, indeed, a very powerful work, to say the least. It is intended that way - I could only list what I know are starting points for these many meanings and many people. Actually, the piece, of itself, went beyond me in intention and meaning to points of which I am only dimly aware.
Brother still crucifies brother - a continual nourishing of agony and violence.
The open mouth is, of course, a protest and a call to end this inhumanity. The viewer should be horrified by this aspect and be moved to ends of peace and humanity by it. Reaction, even against this piece, is good. It must have its effect. Man too often is more anxious to escape facing his guilt and inhumanity - to favor a more relaxed superficial attitude.
