Whether sacred doctrine is nobler than other sciences?

Objections

Objection 1 : It seems that sacred doctrine is not nobler than other sciences; for the nobility of a science depends on the certitude it establishes. But other sciences, the principles of which cannot be doubted, seem to be more certain than sacred doctrine; for its principles---namely, articles of faith---can be doubted. Therefore other sciences seem to be nobler.
Objection 2 : Further, it is the sign of a lower science to depend upon a higher; as music depends on arithmetic. But sacred doctrine does in a sense depend upon philosophical sciences; for Jerome observes, in his Epistle to Magnus, that "the ancient doctors so enriched their books with the ideas and phrases of the philosophers, that thou knowest not what more to admire in them, their profane erudition or their scriptural learning." Therefore sacred doctrine is inferior to other sciences.
