Important: For the record, I would like to admit that question does not - I repeat, does not - apply to my case. In actuality, it is something in the context of my next novel.
A main character of mine, a devout Roman Catholic of the Roman Rite, has a cousin who is not a Catholic. This cousin in question is neither Protestant nor Eastern Orthodox; she follows a form of paganism and heathenism that borderlines toward the ‘occult’.
What exactly should this character do to convince this cousin to become Catholic?
Any suggestions will be accepted.
