les is to natural knowledge, since the articles of faith
are the first principles of knowledge by grace, as was shown above
(Q. 1, A. 7). Now the understanding of principles is possessed in
equal degree by all men. Therefore faith is possessed in equal degree
by all the faithful.

_On the contrary,_ Wherever we find great and little, there we find
more or less. Now in the matter of faith we find great and little,
for Our Lord said to Peter (Matt. 14:31): "O thou of little faith,
why didst thou doubt?" And to the woman he said (Matt. 15: 28): "O
woman, great is thy faith!" Therefore faith can be greater in one
than in another.

_I answer that,_ As stated above (I-II, Q. 52, AA. 1, 2; I-II, Q. 112,
A. 4), the quantity of a habit may be considered from two points of
view: first, on the part of the object; secondly, on the part of its
participation by the subject.

Now the object of faith may be considered in two ways: first, in
respect of its formal aspect; secondly, in respect of the material
object which is proposed to be believed. Now the formal object of
faith is one and simple, namely the First Truth, as stated above (Q.
1, A. 1). Hence in this respect there is no diversity of faith among
believers, but it is specifically one in all, as stated above (Q. 4,
A. 6). But the things which are proposed as the matter of our belief
are many and can be received more or less explicitly; and in this
respect one man can believe explicitly more things than another, so
that faith can be greater in one man on account of its being more
explicit.

If, on the other hand, we consider faith from the point of view of
its participation by the subject, this happens in two ways, since the
act of faith proceeds both from the intellect and from the will, as
stated above (Q. 2, AA. 1, 2; Q. 4, A. 2). Consequently a man's faith
may be described as being greater, in one way, on the part of his
intellect, on account of its greater certitude and firmness, and, in
another way, on the part of his will, on account of his greater
promptitude, devotion, or confidence.

Reply Obj. 1: A man who obstinately disbelieves a thing that is of
faith, has not the habit of faith, and yet he who does not explicitly
believe all, while he is prepared to believe all, has that habit. In
this respect, one man has greater faith than another, on the part of
the object, in so far as he believes more things, as stated above.

Reply Obj. 2: It is essential to faith t
