This might sound maybe a little bit too obvious, but it is not. Unless you know Hebrew and Greek, or Latin, you want to stick to your English translation of the Bible. But, alas, one of the most popular English translations of the Bible — the King James Version — dates back to 1611 and does not follow the Catholic canon. Some more recent versions might be more readable for contemporary readers, and may include devotionals, footnotes, and other interesting resources. You might want to try the Catholic edition of the Revised Standard Version.
