e rule, but to his own will. Hence it is evident
that a heretic who obstinately disbelieves one article of faith, is
not prepared to follow the teaching of the Church in all things; but
if he is not obstinate, he is no longer in heresy but only in error.
Therefore it is clear that such a heretic with regard to one article
has no faith in the other articles, but only a kind of opinion in
accordance with his own will.

Reply Obj. 1: A heretic does not hold the other articles of faith,
about which he does not err, in the same way as one of the faithful
does, namely by adhering simply to the Divine Truth, because in order
to do so, a man needs the help of the habit of faith; but he holds
the things that are of faith, by his own will and judgment.

Reply Obj. 2: The various conclusions of a science have their
respective means of demonstration, one of which may be known without
another, so that we may know some conclusions of a science without
knowing the others. On the other hand faith adheres to all the
articles of faith by reason of one mean, viz. on account of the First
Truth proposed to us in Scriptures, according to the teaching of the
Church who has the right understanding of them. Hence whoever
abandons this mean is altogether lacking in faith.

Reply Obj. 3: The various precepts of the Law may be referred either
to their respective proximate motives, and thus one can be kept
without another; or to their primary motive, which is perfect
obedience to God, in which a man fails whenever he breaks one
commandment, according to James 2:10: "Whosoever shall . . . offend
in one point is become guilty of all."

FOURTH ARTICLE [II-II, Q. 5, Art. 4]

Whether Faith Can Be Greater in One Man Than in Another?

Objection 1: It would seem that faith cannot be greater in one man
than in another. For the quantity of a habit is taken from its
object. Now whoever has faith believes everything that is of faith,
since by failing in one point, a man loses his faith altogether, as
stated above (A. 3). Therefore it seems that faith cannot be greater
in one than in another.

Obj. 2: Further, those things which consist in something supreme
cannot be "more" or "less." Now faith consists in something supreme,
because it requires that man should adhere to the First Truth above
all things. Therefore faith cannot be "more" or "less."

Obj. 3: Further, faith is to knowledge by grace, as the understanding
