For anyone wanting to memorise the Baltimore Catechism.
First, install Anki – a nifty little open source program available for Windows, Mac, Linux, iPhone, Android, FreeBSD and even Nintendo DS.
Next start up the program and go to File > Download > Shared Decks. Type Catechism in the search box and that should bring up “Baltimore Catechism”. Install that one and you are ready to go!
Anki defaults to introducing 20 new cards each day, but you can change this to 2 or 3 or whatever you’re more comfortable with. It aims to review each card just before you’re likely to forget it. It’s called a Spaced Repetition Learning System. You can read more about the theory in this Wikipedia article.
The Baltimore Catechism No2 deck has 421 questions. You might be doing it bit by bit in another program such as the Classic Catechism course from CLAA. The cards are tagged by lesson and question number, so you can select which question numbers you wish to work on. Otherwise it just ploughs through from beginning to end.
The deck was made from the Project Gutenberg text of the Baltimore Catechism No 2 – etext #14552. The imprimatur is from 1885 but the fasting rules have been updated in accordance with the 1977 edition.
The text was converted using Vim with much reference to Vim Regular Expressions 101. It only took a few hours but if you find it useful, feel free to drop me a line. If you feel inclined to make a donation, consider Aid to the Church in Need or the Anki project itself.
UPDATE: ankiweb.net deletes accounts that haven’t been active, so I think the actual deck I made has been deleted, but this time I checked (July 2016) there’s a Baltimore Catechism No 3 available. Here’s my update with deck at Brandt Lab.
