/summa/FS/FSVI/FS_Q101:
We must now consider the ceremonial precepts: and first we must consider them in themselves; secondly, their cause; thirdly, their duration. Under the first head there are four points of inquiry:
(1) The nature of the ceremonial precepts;
(2) Whether they are figurative?
(3) Whether there should have been many of them?
(4) Of their various kinds.
