A Proper Church

[A list of questions that Bishops were to ask while investigating a Church]
1. ... after that they should examine the church building all around, to see if it is well roofed and vaulted and to make sure that no doves or other birds make their nests there - this last because of the uncleanliness of their droppings and the noisy disturbances of which they are capable.
3. [They must inquire] if hay, grain, or anything of that sort is kept in the church.
4. Then they should go up to the altar, and consider what sort of equipment it has; how much is new, how much old, and how cleanly it is maintained.
10. [They must inquire] if it has a complete Missal, book of Lessons, and book of Antiphons. For without these mass cannot be perfectly celebrated.
12. They must inqurie about the lighting of the church ...
15. They should also consider whether the entry to the church is strong enough and closed frequently enough to escape pollution from any unclean deed.
