The answer to my question is probably on this board, but I'm not doing a very good job at finding it. And, this may not be the best board, it is just my best guess.
I want to explain the value, meaning, and purpose of a Baptism/Chrismation cross to my children. (Actually, what is the best way to refer to it?) But, I don't have any words for it.
Although I grew up Orthodox, I've had so little genuine instruction, I know less than most Catachumins (I know, my spelling is terrible. You should see it without the spellchecker!

).
Can someone give me a sort of simple explaination for my kids, and then a place to get better answers for myself?
