Is it appropriate to engrave on the cross?

It's not suitable for lettering on the cross, especially if you have a dragon on your name. In Christianity, dragon means devil, and Christians are very sensitive to this word. It's not appropriate to dedicate the cross engraved with the dragon to your girlfriend. The cross is a standard symbol of Christianity and is not suitable for lettering. A normal cross is not allowed to have any words, only the relief of Jesus being crucified is allowed.
