Whether sacrilege is a special sin?

Objections

Objection 1 : It would seem that sacrilege not a special sin. It is stated (XVII, qu. iv) "They are guilty of sacrilege who through ignorance sin against the sanctity of the law, violate and defile it by their negligence." But this is done in every sin, because sin is "a word, deed or desire contrary to the law of God," according to Augustine (Contra Faust. xxi, 27). Therefore sacrilege is a general sin.
Objection 2 : Further, no special sin is comprised under different kinds of sin. Now sacrilege comprised under different kinds of sin, for instance under murder, if one kill a priest under lust, as the violation of a consecrate virgin, or of any woman in a sacred place under theft, if one steal a sacred thing. Therefore sacrilege is not a special sin.
Objection 3 : Further, every special sin is to found apart from other sins as the Philosopher states, in speaking of special justice (Ethic. v, 11). But, seemingly, sacrilege is not to be found apart from other sins; for it is sometimes united to theft, sometimes to murder, as stated in the preceding objection. Therefore it is not a special sin.
