The correct term is not Christian/Biblical names - it is
Anglicised name.
When we state something as being a Christian/Biblical name, we mean
that the name is derived from the Bible.
An Anglicised name, on the other hand, means that one wants to take
on an angmoh-type name totally disregarding the origin.
I know of radical pastors who think their members should not use
names honouring Greek/Roman gods, like Diana or June.
