[Hermann the Cherusker]

OK, I can see a crucifix being a reminder of the sacrifice... I do not believe Christ wants us to be looking at a image of what you believe to be what He looked like

"And I saw: and behold in the midst of the throne and of the four living creatures and in the midst of the ancients, a Lamb standing, as it were slain" (Apocalypse 5.6)

[Zavien Doombringer]

"a Lamb standing, as it were slain"

Ok, it's a lamb, a baby sheep... Symbolic of Christ, who WAS slain.
