If you would like to know more about Catholics and their beliefs then you should read:
The book describes itself as "a frank and honest guide". I would add "light-hearted and enlightening".
You could buy your own copy (ISBN 0-85231-089-7) or you could contact the Parish Priest for details of the Rite of Christian Initiation in Adulthood (RCIA).
Preparation for RCIA is done during a series of sessions and includes a free copy of "How to survive being married to a Catholic". There are no fees and no obligations.
Non-Catholics and Catholics needing a "refresher course" are all welcome.
