... my best friend is fond of referring to Catholics as private club members. I try to tell her, while yes it is a club to some extent, it isn't exclusive. Maybe she just doesn't understand the intrinsic nature that Catholicism enmeshes itself into your very core. It's not something to do on a Sunday or simply a preference for liturgical styles. Catholicism is so much more than just another denomination to chose from in the spiritual gumbo of religions.
It's the Truth.
To her this declaration sounds arrogant. I am not really sure what to do about.
