I got that information from where I get all my Catholic information, from other Catholics...That came from a piece posted by a Catholic in a censored thread...
Well, there's your problem.
A more intellectually respectable source of Catholic information would be from official teachers or official summaries of the teachings e.g. the Catechism, which is searchable (LINK)in a couple of mouse clicks.
If you want to get information about the relationship between biliary metal stents and air embolism, you could talk to a guy who has a stent, or you could go to cardiologists or medical journals. If it's a matter of life or death to you, I'd recommend the latter.
**I get all my Catholic information, from other Catholics**
This is making you sound as though you are a Catholic. Is that true?
