THIRD ARTICLE [I-II, Q. 67, Art. 3]

Whether Faith Remains After This Life?

Objection 1: It would seem that faith remains after this life.

Because faith is more excellent than science. Now science remains

after this life, as stated above (A. 2). Therefore faith remains also.

Obj. 2: Further, it is written (1 Cor. 3:11): "Other foundation no

man can lay, but that which is laid; which is Christ Jesus," i.e.

faith in Jesus Christ. Now if the foundation is removed, that which

is built upon it remains no more. Therefore, if faith remains not

after this life, no other virtue remains.

Obj. 3: Further, the knowledge of faith and the knowledge of glory

differ as perfect from imperfect. Now imperfect knowledge is

compatible with perfect knowledge: thus in an angel there can be

"evening" and "morning" knowledge [*Cf. I, Q. 58, A. 6]; and a man

can have science through a demonstrative syllogism, together with

opinion through a probable syllogism, about one same conclusion.

Therefore after this life faith also is compatible with the knowledge

of glory.

_On the contrary,_ The Apostle says (2 Cor. 5:6, 7): "While we are in

the body, we are absent from the Lord: for we walk by faith and not

by sight." But those who are in glory are not absent from the Lord,

but present to Him. Therefore after this life faith does not remain

in the life of glory.

_I answer that,_ Opposition is of itself the proper cause of one

thing being excluded from another, in so far, to wit, as wherever two

things are opposite to one another, we find opposition of affirmation

and negation. Now in some things we find opposition in respect of

contrary forms; thus in colors we find white and black. In others we

find opposition in respect of perfection and imperfection: wherefore

in alterations, more and less are considered to be contraries, as

when a thing from being less hot is made more hot (Phys. v, text.

19). And since perfect and imperfect are opposite to one another, it

is impossible for perfection and imperfection to affect the same

thing at the same time.

Now we must take note that sometimes imperfection belongs to a

thing's very nature, and belongs to its species: even as lack of

reason belongs to the very specific nature of a horse and an ox. And

since a thing, so long as it remains the same identically, cannot

pass from one species to another, it follows that if such an

imperfection be removed, the species of that thing is changed: even

as it would no longer be an ox or a horse, were it to be rational.

Sometimes, however, the imperfection does not belong to the specific

nature, but is accidental to the individual by reason of something

else; even as sometimes lack of reason is accidental to a man,

because he is asleep, or because he is drunk, or for some like

reason; and it is evident, that if such an imperfection be removed,

the thing remains substantially.

Now it is clear that imperfect knowledge belongs to the very nature

of faith: for it is included in its definition; faith being defined

as "the substance of things to be hoped for, the evidence of things

that appear not" (Heb. 11:1). Wherefore Augustine says (Tract. xl in

Joan.): "What is faith? Believing without seeing." But it is an

imperfect knowledge that is of things unapparent or unseen.

Consequently imperfect knowledge belongs to the very nature of faith:

therefore it is clear that the knowledge of faith cannot be perfect

and remain identically the same.

But we must also consider whether it is compatible with perfect

knowledge: for there is nothing to prevent some kind of imperfect

knowledge from being sometimes with perfect knowledge. Accordingly we

must observe that knowledge can be imperfect in three ways: first, on

the part of the knowable object; secondly, on the part of the medium;

thirdly, on the part of the subject. The difference of perfect and

imperfect knowledge on the part of the knowable object is seen in the

"morning" and "evening" knowledge of the angels: for the "morning"

knowledge is about things according to the being which they have in

the Word, while the "evening" knowledge is about things according as

they have being in their own natures, which being is imperfect in

comparison with the First Being. On the part of the medium, perfect

and imperfect knowledge are exemplified in the knowledge of a

conclusion through a demonstrative medium, and through a probable

medium. On the part of the subject the difference of perfect and

imperfect knowledge applies to opinion, faith, and science. For it is

essential to opinion that we assent to one of two opposite assertions

with fear of the other, so that our adhesion is not firm: to science

it is essential to have firm adhesion with intellectual vision, for

science possesses certitude which results from the understanding of

principles: while faith holds a middle place, for it surpasses

opinion in so far as its adhesion is firm, but falls short of science

in so far as it lacks vision.

Now it is evident that a thing cannot be perfect and imperfect in the

same respect; yet the things which differ as perfect and imperfect

can be together in the same respect in one and the same other thing.

Accordingly, knowledge which is perfect on the part of the object is

quite incompatible with imperfect knowledge about the same object;

but they are compatible with one another in respect of the same

medium or the same subject: for nothing hinders a man from having at

one and the same time, through one and the same medium, perfect and

imperfect knowledge about two things, one perfect, the other

imperfect, e.g. about health and sickness, good and evil. In like

manner knowledge that is perfect on the part of the medium is

incompatible with imperfect knowledge through one and the same

medium: but nothing hinders them being about the same subject or in

the same subject: for one man can know the same conclusions through a

probable and through a demonstrative medium. Again, knowledge that is

perfect on the part of the subject is incompatible with imperfect

knowledge in the same subject. Now faith, of its very nature,

contains an imperfection on the part of the subject, viz. that the

believer sees not what he believes: whereas bliss, of its very

nature, implies perfection on the part of the subject, viz. that the

Blessed see that which makes them happy, as stated above (Q. 3, A.

8). Hence it is manifest that faith and bliss are incompatible in one

and the same subject.

Reply Obj. 1: Faith is more excellent than science, on the part of

the object, because its object is the First Truth. Yet science has a

more perfect mode of knowing its object, which is not incompatible

with vision which is the perfection of happiness, as the mode of

faith is incompatible.

Reply Obj. 2: Faith is the foundation in as much as it is knowledge:

consequently when this knowledge is perfected, the foundation will be

perfected also.

The Reply to the Third Objection is clear from what has been said.
