As with all of Alex's newartbots, the task is twofold in writing the rules:
i) to make sure that articles that should be included are included; ii) to eliminate false friends.
To this end, the inclusion of a new article, by an author, in the Christianity category, is the most reliable method of picking up relevant new articles. That said there are many articles on Christianity that are not included in the Christianity category. Hence the text based rules.
No other rule should have 105 points, as there is always a conceivable reason why a word might be a false friend.
Rules with many points, are mostly for technical terms, that would very rarely occur outwith of a Christianity-themed article. Rules with few points possess great potential for 'false friendship', but together with many such others, would suggest that the article has a Christianity-based theme.
