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.

Context

“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 that one should give the first place to the First Truth.” source
