Summa Theologica

We must now consider the vices which pertain to irreligion, whereby sacred things are treated with irreverence. We shall consider (1) Sacrilege; (2) Simony.

Under the first head there are four points of inquiry:

(1) What is sacrilege?

(2) Whether it is a special sin?

(3) Of the species of sacrilege;

(4) Of the punishment of sacrilege.
