There are some names with a Christian background which are commonplace and acceptable to use. Names like Mary, John, Noah, and Abigail.
There are others that I think are lovely but my husband says shouldn't really be used by us as we are not religious ourselves. Names like Evangeline, Gabriel, Isaiah, and Emanuella.
I would be interested to hear others thoughts on this, especially those of practicing Christians. For full disclosure we are both white, and although I really like these names I would realistically be unlikely to use them.
