I think I'm confused....

You need a catholic name for baptism???? First I've heard of this. What is a "catholic" name? A biblical one??

Or are you talking about Confirmation when you take a Saint's name?

still a very confused catholic......

.....so I looked at the site.

Giving a child a name that is obviously anti-Christian could suggest a lack of understanding of the meaning of Baptism, and would not make sense. [emphasis added]

I'm guessing here that they would probably question why you are calling your child "Lucifer" as opposed to "George".
