Whether those things that are of faith should be divided into certain articles?

Objections

Objection 1 : It would seem that those things that are of faith should not be divided into certain articles. For all things contained in Holy Writ are matters of faith. But these, by reason of their multitude, cannot be reduced to a certain number. Therefore it seems superfluous to distinguish certain articles of faith.
Objection 2 : Further, material differences can be multiplied indefinitely, and therefore art should take no notice of them. Now the formal aspect of the object of faith is one and indivisible, as stated above (Article [1]), viz. the First Truth, so that matters of faith cannot be distinguished in respect of their formal object. Therefore no notice should be taken of a material division of matters of faith into articles.
Objection 3 : Further, it has been said by some [*Cf. William of Auxerre, Summa Aurea] that "an article is an indivisible truth concerning God, exacting [arctans] our belief." Now belief is a voluntary act, since, as Augustine says (Tract. xxvi in Joan.), "no man believes against his will." Therefore it seems that matters of faith should not be divided into articles.
