No. 3: Get the whole story! When selecting a Bible, look for a Catholic edition.
A Catholic edition will include the Church's complete list of sacred books along with introductions and notes for understanding the text. A Catholic edition will have an imprimatur notice on the back of the title page. An imprimatur indicates that the book is free of errors in Catholic doctrine.
