Why is Angelica Rosechu Catholic, when Chris (was) Protestant?

In Sonichu #3 we're properly introduced to Angelica; she was raised by Catholic nuns. Why would Chris write her character this way? Throughout his life his family has only went to Protestant churches, with Bob and Barb identifying as Methodist and Presbyterian respectively. Does Chris ALSO get his religious views from media, despite having attended multiple churches in his real life already?
